皆様、産業技術総合研究所の北村です。今年10月にニュージーランドで開催される FTSCS2013 の論文募集の案内をお送りいたします。是非論文投稿をご検討下さい。 --------------------------------------------------------------------- Call for Papers FTSCS 2013 2nd International Workshop on Formal Techniques for Safety-Critical Systems Queenstown, New Zealand, October 29, 2013 (satellite workshop of ICFEM 2013) http://www.ftscs.org --------------------------------------------------------------------- *** Science of Computer Programming special issue *** *** Springer CCIS proceedings *** Aims and Scope: There is an increasing demand in industry to use formal methods to achieve software-independent verification and validation of safety-critical systems, e.g., in fields such as avionics, automotive, medical, and other cyber-physical systems. Newer standards, such as DO-178C (avionics) and ISO 26262 (automotive), emphasize the need for formal methods and model-based development, speeding up the adaptation of such methods in industry. The aim of this workshop is to bring together researchers and engineers who are interested in the application of formal and semi-formal methods to improve the quality of safety-critical computer systems. In particular, FTSCS strives strives to promote research and development of formal methods and tools for industrial applications, and is particularly interested in industrial applications of formal methods. Specific topics include, but are not limited to: * case studies and experience reports on the use of formal methods for analyzing safety-critical systems, including avionics, automotive, medical, and other kinds of safety-critical and QoS-critical systems * methods, techniques and tools to support automated analysis, certification, debugging, etc., of complex safety/QoS-critical systems * analysis methods that address the limitations of formal methods in industry (usability, scalability, etc.) * formal analysis support for modeling languages used in industry, such as AADL, Ptolemy, SysML, SCADE, Modelica, etc. * code generation from validated models. The workshop will provide a platform for discussions and the exchange of innovative ideas, so submissions on work in progress are encouraged. Invited speaker: TBA Submission: We solicit submissions reporting on: A- original research contributions (15 pages max, LNCS format); B- applications and experiences (15 pages max, LNCS format); C- surveys, comparisons, and state-of-the-art reports (15 pages max, LNCS format); D- tool papers (5 pages max, LNCS format); E- position papers and work in progress (5 pages max, LNCS format) related to the topics mentioned above.

APLAS 2013 second call for papers
by Chung-chieh Shan 02 Jun '13

02 Jun '13

APLASの締め切りが6月14日に迫って来ました。重複をご容赦下さい。 =============================================================== APLAS 2013 11th Asian Symposium on Programming Languages and Systems 9-11 December 2013 Melbourne, Australia (colocated with CPP 2013) CALL FOR PAPERS =============================================================== ========== BACKGROUND ========== APLAS aims to stimulate programming language research by providing a forum for the presentation of latest results and the exchange of ideas in programming languages and systems. APLAS is based in Asia, but is an international forum that serves the worldwide programming language community. APLAS is sponsored by the Asian Association for Foundation of Software (AAFS) founded by Asian researchers in cooperation with many researchers from Europe and the USA. Past APLAS symposiums were successfully held in Kyoto ('12), Kenting ('11), Shanghai ('10), Seoul ('09), Bangalore ('08), Singapore ('07), Sydney ('06), Tsukuba ('05), Taipei ('04) and Beijing ('03) after three informal workshops. Proceedings of the past symposiums were published in Springer's LNCS. ====== TOPICS ====== The symposium is devoted to foundational and practical issues in programming languages and systems. Papers are solicited on topics such as * semantics, logics, foundational theory; * design of languages, type systems and foundational calculi; * domain-specific languages; * compilers, interpreters, abstract machines; * program derivation, synthesis and transformation; * program analysis, verification, model-checking; * logic, constraint, probabilistic and quantum programming; * software security; * concurrency and parallelism; * tools and environments for programming and implementation. Topics are not limited to those discussed in previous symposiums. Papers identifying future directions of programming and those addressing the rapid changes of the underlying computing platforms are especially welcome. Demonstration of systems and tools in the scope of APLAS are welcome to the System and Tool presentations category. Authors concerned about the appropriateness of a topic are welcome to consult with program chair prior to submission. ========== SUBMISSION ========== We solicit submissions in two categories: *Regular research papers* describing original scientific research results, including tool development and case studies. Regular research papers should not exceed 16 pages in the Springer LNCS format, including bibliography and figures. They should clearly identify what has been accomplished and why it is significant. Submissions will be judged on the basis of significance, relevance, correctness, originality, and clarity. In case of lack of space, proofs, experimental results, or any information supporting the technical results of the paper could be provided as an appendix or a link to a web page, but reviewers are not obliged to read them. *System and Tool presentations* describing systems or tools that support theory, program construction, reasoning, or program execution in the scope of APLAS. System and Tool presentations are expected to be centered around a demonstration. The paper and the demonstration should identify the novelties of the tools and use motivating examples. System and Tool papers should not exceed 8 pages in the Springer LNCS format, including bibliography and figures. Submissions will be judged based on both the papers and the described systems or tools. It is highly desirable that the tools are available on the web. Papers should be submitted electronically via the submission web page: https://www.easychair.org/conferences/?conf=aplas2013 Acceptable formats are PostScript or PDF. Submitted papers must be unpublished and not submitted for publication elsewhere. Papers must be written in English. The proceedings will be published as a volume in Springer's LNCS series. Accepted papers must be presented at the conference. (While the general chair and the program chair cannot submit papers, other members of the program committee can.) ===== DATES ===== Abstract due: 10 June 2013 (Monday), 23:59 UTC Submission due: 14 June 2013 (Friday), 23:59 UTC Notification: 26 August 2013 (Monday) Final paper due: 19 September 2013 (Thursday) Conference: 9-11 December 2013 (Monday-Wednesday) ========== ORGANIZERS ========== General chair: Peter Schachte (University of Melbourne) Program chair: Chung-chieh Shan (Indiana University) Program committee: Filippo Bonchi (CNRS, ENS-Lyon, France) Yu-Fang Chen (Academia Sinica, Taiwan) Shigeru Chiba (The University of Tokyo, Japan) Jacques Garrigue (Nagoya University, Japan) Robert Glück (University of Copenhagen, Denmark) R.

KEOD special session
by 小野寛晰 31 May '13

31 May '13

皆様以下のメールを代理投稿します。　小野寛晰 ---------------------------------------- Dear Madam/Sir, I would like to announce the KEOD’s Special Session (this year in Vilamoura, Portugal) devoted to formal and non-formal aspects of nonmonotonicity. Strict applying of the definition of nonmonotonic inference shows that many examples for nonmonotonicity of human thinking as well as constructions, traditionally understood as nonmonotonic have nothing common with the negation of well known Tarski’s condition for monotonic operation. A rejection from nonmonotonic interpretation of those examples and constructions opens new perspectives in researches on human thinking. http://www.keod.ic3k.org/non-nonmonotonicity.aspx With kind regards, Piotr Lukowski - Chair of KEOD’s Special Session: “Non-nonmonotonicity” Department of Cognitive Science Institute of Psychology University of Lodz, Poland

Kobe Colloquium on Logic, Statistics and Informatics, May 28 (Daisuke Ikegami)
by Joerg Brendle 23 May '13

23 May '13

Kobe Colloquium on Logic, Statistics and Informatics 以下の要領でコロキウムを開催します。日時：2013年5月28日（火）13:20-14:50 講演者：Daisuke Ikegami (University of California, Berkeley) 場所：神戸大学自然科学総合研究棟3号館4階421室（プレゼンテーション室） ============================================================ 題目： Inner models from logics アブストラクト： The goal of this research is to construct a model of set theory which is "close to" HOD but easier to analyze. The motivation comes from Woodin's HOD Conjecture, which states that HOD is very "close to" V under the presence of a very strong large cardinal (extendible cardinal). HOD Conjecture is closely related to the problem of constructing a canonical extender model with a supercompact cardinal and it has striking applications to the theory of large cardinals without the Axiom of Choice. To solve HOD Conjecture, one would expect a fine analysis of HOD. The difficulty of the analysis of HOD lies in the fact that HOD is very "non-absolute", e.g., one could force V = HOD with a proper class partial order. Given that HOD is obtained using full second order logic in the same way as Gödel's constructible universe L via first order logic, in this talk, we use Boolean valued higher order logics to construct inner models of set theory which are more "absolute" than HOD and investigate the properties of the models. ============================================================ 交通：阪急六甲駅またはJR六甲道駅から神戸市バス36系統「鶴甲団地」行きに乗車，「神大本部工学部前」停留所下車，徒歩すぐ． http://www.kobe-u.ac.jp/info/access/rokko/rokkodai-dai2.htm 連絡先：ブレンドレヨーグ brendle(a)kurt.scitec.kobe-u.ac.jp

Monographs by Downey and Hirschfeldt, and by Nies account for the recent research activities in the area. In spite of much work, research on randomness of infinite strings has excluded the investigation of algorithmic randomness for infinite algebraic structures such graphs, trees, groups or more generally universal algebras. In this talk, we provide a framework for reasoning about algorithmic randomness for various classes of infinite structures.

A new computational model, or a new feature in a traditional one, usually is reflected in a new family of programming languages, and new paradigms of software development. The aim of this workshop is to bring together researchers who are currently developing new computational models or new features for traditional computational models, in order to foster their interaction, to provide a forum for presenting new ideas and work in progress, and to enable newcomers to learn about current activities in this area. DCM 2013 will be a one-day satellite event of CONCUR 2013. Topics of interest include all abstract models of computation and their applications to the development of programming languages and systems: - quantum computation, including implementations and formal methods in quantum protocols; - probabilistic computation and verification in modelling situations; - chemical, biological and bio-inspired computation, including spatial models, self-assembly, growth models; - general concurrent models including the treatment of mobility; - infinitary models of computation; - trust, and security; information-theoretic ideas in computing. SUBMISSION ---------- Submit your paper in PDF format via the conference EasyChair submission page: http://www.easychair.org/conferences/?conf=dcm2013 Submissions should be an abstract of at most 5 pages, written in English.

浦本武雄さん（京大数学）によるご講演（来週火曜，4/30）

26 Apr '13

みなさま，東京大学の蓮尾です．来週は研究室のセミナーに浦本武雄さん（京都大学数学教室D3）をお招きして，形式言語理論と圏論的双対性の関連についての結果をお話いただきます．どうかご自由にご参加ください．どうかよろしくお願いいたします．それでは！蓮尾一郎研究室ウェブページ： https://www-mmm.is.s.u-tokyo.ac.jp/indexj.html ============ Tue 30 April 2013, 15:30-17:30 Takeo Uramoto (Dept. Mathematics, Kyoto University) Tannaka-style reconstruction theorem for profinite monoids with an application to Eilenberg-Reiterman's variety theory 理学部7号館1階 102教室 Room 102, School of Science Bldg. No. 7 アクセス： https://www-mmm.is.s.u-tokyo.ac.jp/indexj.html （一番下） Access: http://www-mmm.is.s.u-tokyo.ac.jp/ (see bottom) Eilenberg-Reiterman's variety theory is one of the central theories in algebraic studies of finite automata and regular languages. In its recent development, Rhodes and Steinberg pointed out that the Boolean algebra of regular languages admits a bialgebra structure and revealed its important role in the duality-theoretic formulation of the variety theory. In this talk, we study the structure of the bialgebra of regular languages using a traditional idea from the linear representation theory of groups. In particular, we aim at clarifying a close connection between algebraic structures on the bialgebra of regular languages and geometric structures of finite automata. Our main result claims that there exists a bijective correspondence between bilinear multiplications of regular languages that are compatible with respect to word decompositions and binary products on finite automata that are stable with respect to simulations. This is proved as a corollary of the Tannaka-style reconstruction theorem for profinite monoids, which is an analogue of the classical Tannaka duality theorem for compact groups and indicates a categorical universality of the Boolean algebra of regular languages with respect to finite automata and simulations.

APLAS 2013 call for papers
by Jacques Garrigue 23 Apr '13

23 Apr '13

Logic-MLの皆様、 12月にオーストラリアのメルボルンで開催されるAPLASの論文募集案内をお送りします。投稿締め切りは6月14日ですので、ご検討をよろしくお願いいたします。 Jacques Garrigue =============================================================== APLAS 2013 11th Asian Symposium on Programming Languages and Systems 9-11 December 2013 Melbourne, Australia (colocated with CPP 2013) CALL FOR PAPERS =============================================================== ========== BACKGROUND ========== APLAS aims to stimulate programming language research by providing a forum for the presentation of latest results and the exchange of ideas in programming languages and systems. APLAS is based in Asia, but is an international forum that serves the worldwide programming language community. APLAS is sponsored by the Asian Association for Foundation of Software (AAFS) founded by Asian researchers in cooperation with many researchers from Europe and the USA. Past APLAS symposiums were successfully held in Kyoto ('12), Kenting ('11), Shanghai ('10), Seoul ('09), Bangalore ('08), Singapore ('07), Sydney ('06), Tsukuba ('05), Taipei ('04) and Beijing ('03) after three informal workshops. Proceedings of the past symposiums were published in Springer's LNCS. ====== TOPICS ====== The symposium is devoted to foundational and practical issues in programming languages and systems. Papers are solicited on topics such as * semantics, logics, foundational theory; * design of languages, type systems and foundational calculi; * domain-specific languages; * compilers, interpreters, abstract machines; * program derivation, synthesis and transformation; * program analysis, verification, model-checking; * logic, constraint, probabilistic and quantum programming; * software security; * concurrency and parallelism; * tools and environments for programming and implementation. Topics are not limited to those discussed in previous symposiums. Papers identifying future directions of programming and those addressing the rapid changes of the underlying computing platforms are especially welcome. Demonstration of systems and tools in the scope of APLAS are welcome to the System and Tool presentations category. Authors concerned about the appropriateness of a topic are welcome to consult with program chair prior to submission. ========== SUBMISSION ========== We solicit submissions in two categories: *Regular research papers* describing original scientific research results, including tool development and case studies. Regular research papers should not exceed 16 pages in the Springer LNCS format, including bibliography and figures. They should clearly identify what has been accomplished and why it is significant. Submissions will be judged on the basis of significance, relevance, correctness, originality, and clarity. In case of lack of space, proofs, experimental results, or any information supporting the technical results of the paper could be provided as an appendix or a link to a web page, but reviewers are not obliged to read them. *System and Tool presentations* describing systems or tools that support theory, program construction, reasoning, or program execution in the scope of APLAS. System and Tool presentations are expected to be centered around a demonstration. The paper and the demonstration should identify the novelties of the tools and use motivating examples. System and Tool papers should not exceed 8 pages in the Springer LNCS format, including bibliography and figures. Submissions will be judged based on both the papers and the described systems or tools. It is highly desirable that the tools are available on the web. Papers should be submitted electronically via the submission web page: https://www.easychair.org/conferences/?conf=aplas2013 Acceptable formats are PostScript or PDF. Submitted papers must be unpublished and not submitted for publication elsewhere. Papers must be written in English. The proceedings will be published as a volume in Springer's LNCS series. Accepted papers must be presented at the conference. (While the general chair and the program chair cannot submit papers, other members of the program committee can.) ===== DATES ===== Abstract due: 10 June 2013 (Monday), 23:59 UTC Submission due: 14 June 2013 (Friday), 23:59 UTC Notification: 26 August 2013 (Monday) Final paper due: 19 September 2013 (Thursday) Conference: 9-11 December 2013 (Monday-Wednesday) ========== ORGANIZERS ========== General chair: Peter Schachte (University of Melbourne) Program chair: Chung-chieh Shan (Indiana University) Program committee: Filippo Bonchi (CNRS, ENS-Lyon, France) Yu-Fang Chen (Academia Sinica, Taiwan) Shigeru Chiba (The University of Tokyo, Japan) Jacques Garrigue (Nagoya University, Japan) Robert Glück (University of Copenhagen, Denmark) R.

Kobe Colloquium on Logic, Statistics and Informatics, May 1 (Rod Downey)
by Joerg Brendle 23 Apr '13

23 Apr '13

Kobe Colloquium on Logic, Statistics and Informatics 以下の要領でコロキウムを開催します。日時：2013年5月1日（水）15:00-16:30 場所：神戸大学自然科学総合研究棟3号館4階421室（プレゼンテーション室）講演者：Rod Downey (Victoria University of Wellington, New Zealand) ======================================================================== 題目：Effectively in Abelian Group Theory アブストラクト：The effectiveness of the theory of abelian groups has been long studied beginning with the work of Mal'cev in the 60's. Nevertheless many problems remain. In this lecture I will discuss ongoing work on questions of effectiveness of categoricity and presentability for computable torsion-free abelian groups and for p-groups. For example, for categoricity, general problem is impossible; for example Downey and Montalban showed that the isomorphism problem for torsion-free abelian groups is Sigma_1^1-complete. The principle difficulty lies in the lack of invariants. However, where there are some invariants there we can salvage some effectiveness. The groups we look at are the completely decomposable ones, which have decompositions of the form oplus_{i in omega} G_i with G_i a subgroup of the additive group of the rationals. Such groups are called homogeneous if G_i=H for all i. Alexander Melnikov and the author have shown that homogeneous computable completely decomposable groups are always Delta_3^0 categorical, this bound is sharp, and have classified when the groups are Delta_2^0 categorical in terms of what are called semilow sets. In more recent work, we have shown that every computable completely decomposable group is Delta_5^0 categorical and that this bound is sharp. Additionally we can show that the index set of such groups is Sigma_7^0. I will also describe ongoing work on Ulm's Theorem. ======================================================================== 交通：阪急六甲駅またはJR六甲道駅から神戸市バス36系統「鶴甲団地」行きに乗車，「神大本部工学部前」停留所下車，徒歩すぐ． http://www.kobe-u.ac.jp/info/access/rokko/rokkodai-dai2.htm 連絡先：ブレンドレヨーグ brendle(a)kurt.scitec.kobe-u.ac.jp

みなさま、東京大学の蓮尾研究室M2の森谷です。蓮尾研究室では4月16日に電気通信大学の中野圭介さんをお迎えしてご講演いただきます。詳細は以下で、事前の登録等は一切不要です。ご興味のある方はぜひお越しください！ ============================================================= Tue 16 April 2013, 15:30-17:30 Keisuke Nakano (Univ. Electro-Communications), 2 Talks 理学部7号館1階 102教室 Room 102, School of Science Bldg. No. 7 Talk 1: Juggling meets coinduction In this talk, I will present an application of coinduction, juggling. Buhler et al. presented a mathematical theory of toss juggling by regarding a toss pattern as an arithmetic function, where the function must satisfy a condition for the pattern to be valid. In this talk, I will formalize their theory in terms of coinduction, reflecting the fact that the validity of toss juggling is related to a property of infinite phenomena. A tactic is implemented for proving the validity of toss patterns in Coq. Additionally, the completeness and soundness of a well-known algorithm for checking the validity is certified. The result exposes a practical aspect of coinductive proofs. Most part of this talk has been presented in CPP 2012. Some open problems also will be introduced. Talk 2: Metamorphism in jigsaw In this talk, I will present a new computation model for metamorphism. A metamorphism is an unfold after a fold, consuming an input by the fold then generating an output by the unfold. It is typically useful for converting data representations, e.g., radix conversion of numbers. Bird and Gibbons have shown that metamorphisms can be incrementally processed in streaming style when a certain condition holds because part of the output can be determined before the whole input is given. However, whereas radix conversion of fractions is amenable to streaming, radix conversion of natural numbers cannot satisfy the condition because it is impossible to determine part of the output before the whole input is completed. In this talk, I present a jigsaw model in which metamorphisms can be partially processed for outputs even when the streaming condition does not hold. The jigsaw model allows us to process metamorphisms in a flexible way that includes parallel computation. We also apply our model to other examples of metamorphisms. Most part of this talk is recently published in Journal of Functional Programming. Additionally, I will present some further work on this work.

Inside the theory of represented spaces though, we can consider the same concepts as special cases of continuity/computability. Using category-theoretic language, an abstract and unifying framework is achieved that allows very simple formulations and proofs corresponding closely to various fundamental results in descriptive set theory. * The seminar is held as a part of the EU FP7 Marie Curie Actions IRSES project COMPUTAL (http://computal.uni-trier.de/).

====================================================== TOPOLOGY, ALGEBRA AND CATEGORIES IN LOGIC (TACL 2013) Conference and Summer School Abstract Submission Deadline (EXTENDED): April 8, 2013 Support Request Deadline: April 21, 2013 ====================================================== The Sixth International Conference (and Summer School) on Topology, Algebra and Categories in conjunction with the 28th Annual Shanks Lecture Series Conference and Shanks Lectures: July 28 - August 1, 2013 Summer School: July 24 - 27, 2013 Department of Mathematics, Vanderbilt University Nashville, Tennessee USA http://www.math.vanderbilt.edu/~tacl2013/ ============================================= Sponsors ------------- National Science Foundation Association for Symbolic Logic Shanks Endowment Vanderbilt University Consortium for Order in Algebra and Logic Invited Speakers (Conference) ------------------------------------------------------- Vladimir Voevodsky, Institute for Advanced Studies (Shanks Lecturer) Bernhard Banaschewski, McMaster University Nick Bezhanishvili, Utrecht University Leo Cabrer, University of Oxford Silvio Ghilardi, University of Milan Rostislav Horcik, Academy of Sciences of the Czech Republic George Metcalfe, University of Bern Alex Simpson, University of Edinburgh Summer School Invited Speakers and Courses ------------------------------------------------------------------------- Grigori Mints, Stanford University (on Proof Theory) Lawrence Moss, Indiana University (on Recursion and Circularity) Francesco Paoli, University of Cagliari (on Algebraic Logic) Peter Selinger, Dalhousie University (on Categorical Logic) Scope of the Conference --------------------------------- Studying logics via semantics is a well-established and very active branch of mathematical logic, with many applications, in computer science and elsewhere. The area is characterized by results, tools and techniques stemming from various fields, including universal algebra, topology, category theory, order, and model theory. The program of the conference TACL 2013 will focus on three interconnecting mathematical themes central to the semantical study of logics and their applications: algebraic, categorical, and topological methods. This is the sixth conference in the series Topology, Algebra and Categories in Logic (TACL, formerly TANCL). Earlier installments of this conference have been organized in Tbilisi (2003), Barcelona (2005), Oxford (2007), Amsterdam (2009), Marseilles (2011). Featured topics --------------------- Contributed talks can deal with any topic dealing with the use of algebraic, categorical or topological methods in either logic or computer science. This includes, but is not limited to, the following areas: * Algebraic structures in CS * Algebraic logic * Coalgebra * Categorical methods in logic * Domain theory * Lattice theory * Lattices with operators * Many-valued and fuzzy logics * Modal logics * Non-classical logics * Ordered topological spaces * Ordered algebraic structures * Point-free topology * Proofs and Types * Residuated structures * Semantics * Stone-type dualities * Substructural logics * Topological semantics of modal logic The Summer School ---------------------------- TACL brings together different disciplines with the goal of exploring problems in logic. Partly due to the success of the TACL conference series, researchers have started employing tools used outside their immediate areas, either individually or in collaboration with specialists in research fields featured in the series. Such interactions have also naturally lead to new directions that combine ideas from two or more research fields. This has been a gradual and arduous process and TACL can boast of having participants that are at least somewhat familiar with most of the featured areas. However, young researchers and students who attend the conference and work in TACL fields have a more restricted and specialized repertoire of tools and knowledge. The goal of the Summer School is to fill the gap and expose such researchers to a variety of methods that can be used to study logic. It will primarily target graduate students and postdocs, but also more senior researchers who are not familiar with aspects of neighboring areas. Prospective Summer School participants should express their interest on the 'Express Interest' page of the TACL 2013 web site by selecting the events that plan to attend (summer school and/or conference). Limited funds for supporting summer school participants are available (mainly through NSF). Those who plan to request financial support should submit a copy of their CV and a letter of support from their PhD advisor or post-doc supervisor (if applicable) to tacl2013(a)gmail.com<mailto:tacl2013@gmail.com> with 'Summer School support request' in the subject line by April 21, 2013. In addition, they need to fill out the financial support form on the 'Support Requests' page by the same date. Registration should also be completed by June 1, 2013. We would appreciate your assistance in advertising the Summer School to interested students. Additional information can be found on the 'Summer School' page of the TACL 2013 web site. Submissions to the Conference ------------------------------------------- Contributed presentations will be of two types: o 20 minutes long presentations in parallel sessions and o featured, 30 minutes long, plenary presentations. The submission of an abstract will be required to be selected for a contributed presentation of either kind. While preference will be given to new work, results that have already been published or presented elsewhere will also be considered. More information on the submission procedure, as well as a link to the EasyChair system, can be found at the conference web site.

[Please circulate. My apologies for cross posting.] 皆様， TLCA(Typed Lambda Calculi and Applications) と RTA(Rewriting Techniques and Applications) の Satellite workshop(COS'13) がEindhovenで開催されます．皆様のご参加・投稿をお待ちしております．群馬大学　藤田憲悦 ------------------------------------------------------------------------------------------------------------------------------------ This is the COS'13 cfp with some changes of dates. While keeping *the deadline of submissions on April the 6th*, we do not require previous abstract submission, and postpone to April the 15th the deadline for contributed talks only (called EXTENDED ABSTRACTS below): Submission: April, 6 2013 (*no previous abstract submission required*) Extended abstract: April, 15 2013 (*new*) Notification: April, 29 2013 (changed) Final version: May, 15 2013 (changed) Workshop: June, 24-25 2013 ============================================================================ Control Operators and their Semantics (COS'13) - Call for Papers Satellite event of RDP'13 June 24 - 25, 2013, Eindhoven, The Nederlands http://cos2013.di.unito.it/ (modified on April, 25th) ============================================================================ Modern programming languages provide sophisticated control mechanisms, commonly referred to as control operators which are widely used to realize a variety of applications. Since we cannot escape control features, it becomes a challenge to provide them with sound reasoning principles. There is a very active research on understanding, manipulating, representing, and reasoning about elaborated non-local control structures, in particular in declarative programming languages such as functional and logic languages. Ideas and results originating from this research area have impact in many other areas of computer science, like distributed and concurrent systems, proof theory, proof mining, web programming and linguistics. For instance, the study of the logical foundations of control operators renewed the study of the connections between proofs and programs via the so-called Curry-Howard correspondence, providing new methods to extract the computational content of classical proofs. The focus of the workshop is on the interplay between syntax and semantics, namely the central question of what a program means and how it does define the intended procedure. This is a crucial issue especially in the case of control operators, since they are as powerful as potentially obscure, and programs that use them are usually more error prone than purely declarative ones. The issue of a better understanding of control is also relevant for communicating across different research areas and communities. More abstract views can be achieved via several means, that include operational semantics of formal calculi, abstract machines, algebraic specifications and rewriting, type assignment systems, denotational semantics and game semantics, category theory and logic, to say the least. Relevant topics include, but are not limited to: - continuations and delimited continuations - categorical models of continuations - compositionality and modularity of control operators - denotational semantics of control, event structures and causality - operational semantics and abstract machines - type systems for control operators - game semantics of programming languages and of logical proofs - usage of control operators in proof search and proof mining - semantics of control operators in logic programming Invited speakers: - Mattew Flatt (Univeristy of Utah) - Thomas Streicher (Universitaet Darmstadt) Program Committee: Zena Ariola University of Oregon Stefano Berardi Turin University Hugo Herbelin INRIA and Laboratoire PPS (Paris 7) Ugo de'Liguoro (chair) Turin Univerisity Ken-etsu Fujita Gunma University Koji Nakazawa Kyoto University Alexis Saurin (co-chair) INRIA and Laboratoire PPS (Paris 7) Submission: authors of original works on the topic of the workshop are invited to submit either a FULL PAPER of up to 20 pages, which has to be unpublished nor submitted elsewhere, or an EXTENDED ABSTRACT of up to 5 pages (to which previous restrictions do not apply) for short presentation at the workshop.

There are two well-known problems with BHK exposed by Kreisel in 1962. First, in the original BHK, any proof vacuously “proves” the negation of any unprovable sentence; this dubious feature ruins constructive connection between a sentence and its proof. Second, original BHK’s treating of universal quantifiers admits unacceptable bogus “proofs” for any true Π1-sentence, e.g., for Fermat’s Last Theorem or the consistency statement. Kreisel offered plausible corrections to BHK which we suggest calling BHK*. The problem of an exact provability interpretation of BHK* turned out to be elusive. For example, BHK- inspired semantics based on computational programs (Realizability, Curry-Howard isomorphism, Intuitionistic Type Theory) though have constituted a major development in logic and computer science, do not satisfy BHK*. In the 1930s, Gödel suggested to define intuitionistic logic via classical provability represented by modal logic S4 and interpret the latter via explicit proofs rather then provability. Later developments of the Logic of Proofs LP in the 1990s opened the door to realizing Gödel’s approach. In this talk, we survey provability semantics obtained by Gödel’s embedding of intuitionistic logic into S4, followed by a realization in the Logic of Proofs. We show that it satisfies BHK* requirements and provides a desired provability foundation for intuitionistic logic. Speaker: Dr. Elena Nogina, The City University of New York Title: Joining Two Gödel's approaches to provability Abstract: In 1933, Gödel suggested S4 as a modal logic of provability but pointed out that S4 was not compatible with a straightforward interpretation of modality as formal provability. This left "a provability semantics without a calculus" and "a provability calculus without a semantics." In 1976, Solovay found that modal logic GL was the logic of formal provability; in 1995, Artemov found a precise provability semantics for S4 via Logic of Proofs LP. In this talk, we introduce logic GLA representing both aforementioned Gödel's approaches to provability, as well as new provability principles which appear as a result of interactions between these models. GLA is supplied with a Kripke-style semantics and the corresponding completeness theorem. Soundness and completeness of GLA with respect to the arithmetical provability semantics is established. 問い合わせ先：日本大学文理学部哲学科飯田隆 iida.takashi19(a)nihon-u.ac.jp 【２】Seminar in Logic and Philosophy of Mathematics 日時：2013年3月26日（火）〜27日（水）場所：神戸大学自然科学総合研究棟3号館4階421室（プレゼンテーション室）プログラム： 3月26日 10:30-12:00 Sergei Artemov (CUNY) Logic of Proofs and Justification (1/2) 13:00-14:30 Elena Nogina (CUNY) On Provability and Explicit Proofs 15:00-16:30 Taishi Kurahashi (Kobe) Syntax and semantics of predicate modal logic of provability 3月27日 10:30-12:00 Sergei Artemov (CUNY) Logic of Proofs and Justification (2/2) 13:00-14:30 Ryota Akiyoshi (Kyoto) Proper Explanation of Brouwer's Fundamental Assumption 15:00-16:30 Hidenori Kurokawa Kreisel's second clause and the theory of constructions Speaker: Sergei Artemov, The City University of New York Title: Logic of Proofs and Justification Abstract: We describe a general logical framework, Justification Logic, for reasoning about epistemic justification. Justification Logic is based on classical propositional logic augmented by justification assertions t:F that read `t is a justification for F.' In this talk, we show how Justification Logic originated from the mathematical proof-theoretical semantics as the Logic of Proofs and then extended to the mainstream epistemology. In the foundations of constructive reasoning, the Logic of Proofs has completed Gödel's effort of the 1930s to find a classical provability interpretation of intuitionistic logic. In epistemology, Justification Logic offered the missing justification component to formal analysis of Knowledge as Justified True Belief approach commonly attributed to Plato. As a case study, we offer a resolution of the Goldman–Kripke ‘Red Barn’ paradox and analyze Russell’s ‘prime minister example’ in Justification Logic. We state a general Correspondence Theorem showing that behind each epistemic modal logic, there is a robust system of justifications. This renders a new, evidence-based foundation for epistemic logic. Speaker: Dr. Elena Nogina, The City University of New York. Title: On Provability and Explicit Proofs Abstract: Gödel's Incompleteness Theorem drew a sharp distinction between explicit proofs and formal provability. In particular, reflection principle "if A is formally provable then A holds" is true but not internally provable, whereas explicit reflection principle "if p is a proof of A, then A holds" is both true and provable. According to Solovay, all valid principles of formal provability are described by Gödel-Löb modal logic GL. Artemov's Logic of Proofs LP describes all valid principles of explicit proofs with a basic set of operations. Some meaningful provability principles require both provability and explicit proofs. E.g., the negative introspection fails in GL as well as in LP, but admits an adequate formulation in mixed language of GL and LP. We introduce logic GLA, that describes, along with GL and LP, all valid principles in the language of proofs and provability. GLA has been supplied with Kripke-style semantics and shown to be complete with respect to the intended arithmetical provability interpretation. 問い合わせ先：神戸大学大学院システム情報学研究科菊池誠 mkikuchi(a)kobe-u.ac.jp

For example, BHK- inspired semantics based on computational programs (Realizability, Curry-Howard isomorphism, Intuitionistic Type Theory) though have constituted a major development in logic and computer science, do not satisfy BHK*. In the 1930s, Gödel suggested to define intuitionistic logic via classical provability represented by modal logic S4 and interpret the latter via explicit proofs rather then provability. Later developments of the Logic of Proofs LP in the 1990s opened the door to realizing Gödel’s approach. In this talk, we survey provability semantics obtained by Gödel’s embedding of intuitionistic logic into S4, followed by a realization in the Logic of Proofs. We show that it satisfies BHK* requirements and provides a desired provability foundation for intuitionistic logic. Speaker: Dr. Elena Nogina, The City University of New York Title: Joining Two Gödel's approaches to provability Abstract: In 1933, Gödel suggested S4 as a modal logic of provability but pointed out that S4 was not compatible with a straightforward interpretation of modality as formal provability. This left "a provability semantics without a calculus" and "a provability calculus without a semantics." In 1976, Solovay found that modal logic GL was the logic of formal provability; in 1995, Artemov found a precise provability semantics for S4 via Logic of Proofs LP. In this talk, we introduce logic GLA representing both aforementioned Gödel's approaches to provability, as well as new provability principles which appear as a result of interactions between these models. GLA is supplied with a Kripke-style semantics and the corresponding completeness theorem. Soundness and completeness of GLA with respect to the arithmetical provability semantics is established. 問い合わせ先：日本大学文理学部哲学科飯田隆 iida.takashi19(a)nihon-u.ac.jp 【２】Seminar in Logic and Philosophy of Mathematics 日時：2013年3月26日（火）〜27日（水）場所：神戸大学自然科学総合研究棟3号館4階421室（プレゼンテーション室）プログラム： 3月26日 10:30-12:00 Sergei Artemov (CUNY) Logic of Proofs and Justification (1/2) 13:00-14:30 Elena Nogina (CUNY) On Provability and Explicit Proofs 15:00-16:30 Taishi Kurahashi (Kobe) Syntax and semantics of predicate modal logic of provability 3月27日 10:30-12:00 Sergei Artemov (CUNY) Logic of Proofs and Justification (2/2) 13:00-14:30 Ryota Akiyoshi (Kyoto) Proper Explanation of Brouwer's Fundamental Assumption 15:00-16:30 Hidenori Kurokawa Kreisel's second clause and the theory of constructions Speaker: Sergei Artemov, The City University of New York Title: Logic of Proofs and Justification Abstract: We describe a general logical framework, Justification Logic, for reasoning about epistemic justification. Justification Logic is based on classical propositional logic augmented by justification assertions t:F that read `t is a justification for F.' In this talk, we show how Justification Logic originated from the mathematical proof-theoretical semantics as the Logic of Proofs and then extended to the mainstream epistemology. In the foundations of constructive reasoning, the Logic of Proofs has completed Gödel's effort of the 1930s to find a classical provability interpretation of intuitionistic logic. In epistemology, Justification Logic offered the missing justification component to formal analysis of Knowledge as Justified True Belief approach commonly attributed to Plato. As a case study, we offer a resolution of the Goldman–Kripke ‘Red Barn’ paradox and analyze Russell’s ‘prime minister example’ in Justification Logic. We state a general Correspondence Theorem showing that behind each epistemic modal logic, there is a robust system of justifications. This renders a new, evidence-based foundation for epistemic logic. Speaker: Dr. Elena Nogina, The City University of New York. Title: On Provability and Explicit Proofs Abstract: Gödel's Incompleteness Theorem drew a sharp distinction between explicit proofs and formal provability. In particular, reflection principle "if A is formally provable then A holds" is true but not internally provable, whereas explicit reflection principle "if p is a proof of A, then A holds" is both true and provable. According to Solovay, all valid principles of formal provability are described by Gödel-Löb modal logic GL. Artemov's Logic of Proofs LP describes all valid principles of explicit proofs with a basic set of operations. Some meaningful provability principles require both provability and explicit proofs. E.g., the negative introspection fails in GL as well as in LP, but admits an adequate formulation in mixed language of GL and LP. We introduce logic GLA, that describes, along with GL and LP, all valid principles in the language of proofs and provability. GLA has been supplied with Kripke-style semantics and shown to be complete with respect to the intended arithmetical provability interpretation. 問い合わせ先：神戸大学大学院システム情報学研究科菊池誠 mkikuchi(a)kobe-u.ac.jp

ICE 2013: Deadline extended until Sunday 24th March
by Ichiro Hasuo 20 Mar '13

20 Mar '13

みなさま，以前お知らせしたワークショップ ICE のご案内です． - 〆切が 3/24 まで延びました． - Short paper や既発表論文の紹介も大歓迎です．みなさま，ぜひご投稿・ご参加を検討ください！蓮尾一郎 http://www-mmm.is.s.u-tokyo.ac.jp/~ichiro/ ====== [- Apologies for multiple copies -] ICE 2013 6th Interaction and Concurrency Experience June 6, 2013, Florence, Italy http://www.discotec.org/workshops/ice2013/ Satellite workshop of DisCoTec 2013 http://www.discotec.org === Highlights === - Innovative selection procedure - ICE welcomes submissions of full papers, short papers, and brief announcements - Invited talks: Davide Sangiorgi & Damien Pous - Special issue of Science of Computer Programming (http://www.journals.elsevier.com/science-of-computer-programming/) === Important Dates === 24 March 2013...................Full paper submission 25 March - 21 April 2013....Reviews, rebuttal, and PC discussion 24 April 2013......................Notification to authors 6 June 2013.......................ICE in Florence 15 Sept 2013.....................Camera-ready for post-proceedings === Scope === Interaction and Concurrency Experiences (ICEs) is a series of international scientific meetings oriented to theoretical computer science researchers with special interest in models, verification, tools and programming primitives for complex interactions. The general scope of the venue includes theoretical and applied aspects of interactions and the synchronization mechanisms used among components of concurrent/distributed systems, related to several areas of computer science in the broad spectrum ranging from formal specification and analysis to studies inspired by emerging computational models. Topics of interest include, but are not limited to: - Process algebra and coordination: transformation, analysis and implementation - Models for distributed coordination and semantics - Techniques and tools for specification, analysis, verification of resilient interactions - Coinductive techniques for reactive systems - Languages, protocols and mechanisms for sound distributed coordination - Logics and types for interactions - Comparison among different coordination and/or execution models - Expressive power of coordination languages and execution models - Formal semantics of coordination languages - Formal verification of distributed coordinated architectures - Relations between different semantic models for coordination languages === Selection Procedure === Since its 1st edition in 2008, the distinguishing feature of ICE has been an innovative paper selection mechanism based on an interactive discussion amongst authors and PC members. During the review phase, each submitted paper is published on a Wiki and associated with a discussion forum. The discussion forum can be accessed by the authors of the paper and by all the PC members not in conflict with the paper. The forum is used by reviewers to ask questions and clarifications to the authors, allowing them to better explain all the aspects of their paper. The evaluation of the paper will keep into account not only the reviews, but also the outcome of the discussion. As witnessed by the past five editions of ICE, this procedure considerably improves the accuracy of the feedback from reviews, the fairness of the selection, the quality of camera-ready papers, and the discussion during the workshop. === The Public Wiki === After the notification, the accepted papers are published on a public forum, in order to initiate public discussions that will trigger and stimulate the scientific debate at the workshop. We believe that this will drive the workshop discussions and let prospective participants interact with each other much earlier than in more traditional events. === Submission Guidelines === We invite for three types of submissions: (1) Full Papers, (2) Short Papers, and (3) Brief Announcements of already Published Papers. Full and short papers to appear in the post-proceedings must report previously unpublished work and not be simultaneously submitted to other conferences/workshops with refereed proceedings. The ICE 2013 post-proceedings will be published in Electronic Proceedings in Theoretical Computer Science (http://eptcs.org/). In addition, we invite for brief announcements of already published results, should the authors be interested in discussing their published research with the ICE community and giving a talk. Brief announcements will not be part of the post-proceedings. Submissions must be made electronically in PDF format via EasyChair (http://www.easychair.org/conferences/?conf=ice2013). Full papers should not exceed 15 pages while short papers and brief announcements should not exceed 5 pages with the EPTCS style (http://style.eptcs.org/). Accepted (full and short) papers and brief announcements must be presented at the workshop by one of the authors. === Special Issue === Extended versions of the best full papers selected by the PC will be invited to appear in a special issue of the journal of Science of Computer Programming (http://www.journals.elsevier.com/science-of-computer-programming/ ). Such contributions will be regularly peer-reviewed according to the standard journal policy, but they will be handled in a shorter time than regular submissions. === Program Committee === Luca Aceto (Reykjavik University, Iceland) Simon Bliudze (EPFL, Switzerland) Laura Bocchi (University of Leicester, UK) Filippo Bonchi (CNRS, France) Roberto Bruni (University of Pisa, Italy) Marcello Bonsangue (Leiden University, The Netherlands) Ornela Dardha (University of Bologna/INRIA, Italy) Ichiro Hasuo (University of Tokyo, Japan) Tobias Heindel (CEA Saclay, France) Ludovic Henrio (CNRS, France) Clemens Kupke (University of Strathclyde, Scotland, UK) Julien Lange (University of Leicester, UK) Antonia Lopes (University of Lisbon, Portugal) Giuliano Losa (EPFL, Switzerland) Claudio A.

====================================================== TOPOLOGY, ALGEBRA AND CATEGORIES IN LOGIC (TACL 2013) Conference and Summer School (Abstract Submission Deadline: April 1, 2013) (Support Request Deadline: April 21, 2013) ====================================================== The Sixth International Conference (and Summer School) on Topology, Algebra and Categories in conjunction with the 28th Annual Shanks Lecture Series Conference and Shanks Lectures: July 28 - August 1, 2013 Summer School: July 24 - 27, 2013 Department of Mathematics, Vanderbilt University Nashville, Tennessee USA http://www.math.vanderbilt.edu/~tacl2013/ ============================================= Sponsors ------------- National Science Foundation Association for Symbolic Logic Shanks Endowment Vanderbilt University Consortium for Order in Algebra and Logic Invited Speakers (Conference) ------------------------------------------------------- Vladimir Voevodsky, Institute for Advanced Studies (Shanks Lecturer) Nick Bezhanishvili, Utrecht University Leo Cabrer, University of Oxford Silvio Ghilardi, University of Milan Rostislav Horcik, Academy of Sciences of the Czech Republic George Metcalfe, University of Bern Alex Simpson, University of Edinburgh Summer School Invited Speakers and Courses ------------------------------------------------------------------------- Grigori Mints, Stanford University (on Proof Theory) Lawrence Moss, Indiana University (on Recursion and Circularity) Francesco Paoli, University of Cagliari (on Algebraic Logic) Peter Selinger, Dalhousie University (on Categorical Logic) Scope of the Conference --------------------------------- Studying logics via semantics is a well-established and very active branch of mathematical logic, with many applications, in computer science and elsewhere. The area is characterized by results, tools and techniques stemming from various fields, including universal algebra, topology, category theory, order, and model theory. The program of the conference TACL 2013 will focus on three interconnecting mathematical themes central to the semantical study of logics and their applications: algebraic, categorical, and topological methods. This is the sixth conference in the series Topology, Algebra and Categories in Logic (TACL, formerly TANCL). Earlier installments of this conference have been organized in Tbilisi (2003), Barcelona (2005), Oxford (2007), Amsterdam (2009), Marseilles (2011). Featured topics --------------------- Contributed talks can deal with any topic dealing with the use of algebraic, categorical or topological methods in either logic or computer science. This includes, but is not limited to, the following areas: * Algebraic structures in CS * Algebraic logic * Coalgebra * Categorical methods in logic * Domain theory * Lattice theory * Lattices with operators * Many-valued and fuzzy logics * Modal logics * Non-classical logics * Ordered topological spaces * Ordered algebraic structures * Point-free topology * Proofs and Types * Residuated structures * Semantics * Stone-type dualities * Substructural logics * Topological semantics of modal logic The Summer School ---------------------------- TACL brings together different disciplines with the goal of exploring problems in logic. Partly due to the success of the TACL conference series, researchers have started employing tools used outside their immediate areas, either individually or in collaboration with specialists in research fields featured in the series. Such interactions have also naturally lead to new directions that combine ideas from two or more research fields. This has been a gradual and arduous process and TACL can boast of having participants that are at least somewhat familiar with most of the featured areas. However, young researchers and students who attend the conference and work in TACL fields have a more restricted and specialized repertoire of tools and knowledge. The goal of the Summer School is to fill the gap and expose such researchers to a variety of methods that can be used to study logic. It will primarily target graduate students and postdocs, but also more senior researchers who are not familiar with aspects of neighboring areas. Prospective Summer School participants should express their interest on the 'Express Interest' page of the TACL 2013 web site by selecting the events that plan to attend (summer school and/or conference). Limited funds for supporting summer school participants are available (mainly through NSF). Those who plan to request financial support should submit a copy of their CV and a letter of support from their PhD advisor or post-doc supervisor (if applicable) to tacl2013(a)gmail.com with 'Summer School support request' in the subject line by April 21, 2013. In addition, they need to fill out the financial support form on the 'Support Requests' page by the same date. Registration should also be completed by June 1, 2013. We would appreciate your assistance in advertising the Summer School to interested students. Additional information can be found on the 'Summer School' page of the TACL 2013 web site. Submissions to the Conference ------------------------------------------- Contributed presentations will be of two types: o 20 minutes long presentations in parallel sessions and o featured, 30 minutes long, plenary presentations. The submission of an abstract will be required to be selected for a contributed presentation of either kind. While preference will be given to new work, results that have already been published or presented elsewhere will also be considered. More information on the submission procedure, as well as a link to the EasyChair system, can be found at the conference web site.

See the new dates in the call for papers below and at the CALCO'13 web page http://coalg.org/calco13/ ========================================================================= CALL FOR PAPERS: CALCO 2013 5th International Conference on Algebra and Coalgebra in Computer Science September 3 - 6, 2013 Warsaw, Poland http://coalg.org/calco13/ ========================================================================= Abstract submission: March 1, 2013 Paper submission: March 8, 2013 Author notification: May 6, 2013 Final version due: June 3, 2013 ========================================================================= -- SCOPE -- CALCO aims to bring together researchers and practitioners with interests in foundational aspects, and both traditional and emerging uses of algebra and coalgebra in computer science. It is a high-level, bi-annual conference formed by joining the forces and reputations of CMCS (the International Workshop on Coalgebraic Methods in Computer Science), and WADT (the Workshop on Algebraic Development Techniques). Previous CALCO editions took place in Swansea (Wales, 2005), Bergen (Norway, 2007), Udine (Italy, 2009) and Winchester (UK, 2011). The fifth edition will be held in Warsaw, the capital of Poland. -- INVITED SPEAKERS -- Andrej Bauer - University of Lubljana, Sl Mikołaj Bojańczyk - Warsaw University, PL Neil Ghani - University of Strathclyde, UK Damien Pous - CNRS, ENS-Lyon, F -- TOPICS OF INTEREST -- We invite submissions of technical papers that report results of theoretical work on the mathematics of algebras and coalgebras, the way these results can support methods and techniques for software development, as well as experience with the transfer of the resulting technologies into industrial practice. We encourage submissions in topics included or related to those listed below. * Abstract models and logics - Automata and languages - Categorical semantics - Modal logics - Relational systems - Graph transformation - Term rewriting - Adhesive categories * Specialised models and calculi - Hybrid, probabilistic, and timed systems - Calculi and models of concurrent, distributed, mobile, and context-aware computing - General systems theory and computational models (chemical, biological, etc.) * Algebraic and coalgebraic semantics - Abstract data types - Inductive and coinductive methods - Re-engineering techniques (program transformation) - Semantics of conceptual modelling methods and techniques - Semantics of programming languages * System specification and verification - Algebraic and coalgebraic specification - Formal testing and quality assurance - Validation and verification - Generative programming and model-driven development - Models, correctness and (re)configuration of hardware/middleware/architectures, - Process algebra -- NEW TOPICS -- This edition of CALCO will feature two new topics, and submission of papers on these topics is especially encouraged. * Corecursion in Programming Languages - Corecursion in logic / constraint / functional / answer set programming - Corecursive type inference - Coinductive methods for proving program properties - Implementing corecursion - Applications * Algebra and Coalgebra in quantum computing - Categorical semantics for quantum computing - Quantum calculi and programming languages - Foundational structures for quantum computing - Applications of quantum algebra -- SUBMISSION GUIDELINES -- Prospective authors are invited to submit full papers in English presenting original research. Submitted papers must be unpublished and not submitted for publication elsewhere. Experience papers are welcome, but they must clearly present general lessons learned that would be of interest and benefit to a broad audience of both researchers and practitioners. As with previous editions, the proceedings will be published in the Springer LNCS series. Final papers should be no more than 15 pages long in the format specified by Springer (see http://www.springer.de/comp/lncs/authors.html). It is recommended that submissions adhere to that format and length. Submissions that are clearly too long may be rejected immediately. Proofs omitted due to space limitations may be included in a clearly marked appendix. Both an abstract and the full paper must be submitted by their respective submission deadlines. A special issue of the open access journal Logical Methods in Computer Science (http://www.lmcs-online.org), containing extended versions of selected papers, is also being planned. Submissions will be handled via EasyChair https://www.easychair.org/conferences/?conf=calco2013 -- BEST PAPER AND BEST PRESENTATION AWARDS -- For the first time, this edition of CALCO will feature two kinds of awards: a best paper award whose recipients will be selected by the PC before the conference and a best presentation award, elected by the participants. -- IMPORTANT DATES -- Abstract submission: February 22, 2013 Paper submission: March 1, 2013 Author notification: May 6, 2013 Final version due: June 3, 2013 -- PROGRAMME COMMITTEE -- Luca Aceto - Reykjavik University, Iceland Jiří Adámek - TU Braunschweig, D Lars Birkedal - IT University of Copenhagen, DK Filippo Bonchi - CNRS, ENS-Lyon, F Corina Cirstea - University of Southhampton, UK Bob Coecke - University of Oxford, UK Andrea Corradini - University of Pisa, I Mai Gehrke - Université Paris Diderot - Paris 7, F H.

The workshop is dedicated to presentation of work in progress and original research proposals. PhD students and young researchers are particularly encouraged to contribute. Attendance at the workshop is open to all - it is anticipated that many CALCO conference participants will want to attend the CALCO Early Ideas workshop (and vice versa). A workshop dedicated to tools based on algebraic and/or coalgebraic principles, CALCO Tools, will be held alongside the main conference, chaired by Lutz Schröder (Friedrich Alexander Universität Erlangen-Nürnberg). Papers of this workshop will be included in the CALCO proceedings. -- CALCO Early Ideas Overview -- The CALCO Early Ideas Workshop invites submissions on the same topics as the CALCO conference: reporting results of theoretical work on the mathematics of algebras and coalgebras, the way these results can support methods and techniques for software development, as well as experience with the transfer of the resulting technologies into industrial practice. The list of topics of particular interest is shown on the main CALCO 2013 page. CALCO Early Ideas presentations will be selected according to originality, significance, and general interest, on the basis of submitted 2-page short contributions. It can be work in progress, a summary of work submitted to a conference or workshop elsewhere, or work that in some other way might be interesting to the CALCO audience. A booklet with the accepted short contributions will be available at the workshop. Submissions will be handled via EasyChair https://www.easychair.org/conferences/?conf=calcoearlyideas2013 The use of LNCS style is strongly encouraged. After the workshop, authors will have the opportunity to submit a full 10-15 page paper on the same topic. The reviewing will be carried out by the CALCO Early Ideas PC, with the support of the CALCO PC. The volume of selected papers will be available online. Authors will retain copyright, and are also encouraged to disseminate the results by subsequent publication elsewhere. http://coalg.org/calco13/workshops.html#ei -- CALCO Early Ideas Dates -- 2-page short contribution submission: May 27, 2013 Notification for short contribution: June 24, 2013 Final short contribution due: July 15, 2013 CALCO Early Idead Workshop: September 2, 2013 10-15 page paper submission: October 15, 2013 Notification for paper: December 15, 2013 Final paper version due: January 15, 2014 -- CALCO Early Ideas Program Committee -- Bartek Klin, University of Warsaw, Poland John Power, University of Bath, UK Monika Seisenberger, Swansea University, UK (chair) -- CALCO-Tools Overview -- CALCO-Tools will take place on the same dates as the main CALCO conference, with no overlap between the technical programmes of the two events. Topics of interest include systems, prototypes, and tools developed specifically for the design, checking, execution, and verification of (co)algebraic specifications, but also tools targeting different application domains while making core or interesting use of (co)algebraic techniques. Tool submissions should not exceed 5 pages in LNCS format. The accepted tool papers will be included in the final proceedings of the conference. The tools should be made available on the web at the time of submission. Each submission will be evaluated by at least three reviewers; one or more of the reviewers will be asked to download and use the tool.

To formulate his finitary standpoint, he attempted to find the fundamental concepts in mathematics. Gentzen's finitism also made this attempt, though he had to extend Hilbert's standpoint due to G\"{o}del's incompleteness theorems. Particularly, in the 1935 consistency proof of $PA$ Gentzen included intuitionistic concepts such as the concept of choice sequences among the fundamental concepts. From philosophical point of view, their formulations of the fundamental concepts in mathematics are of remarkable importance. In this talk, we claim that by admitting choice sequences Gentzen extended the finitist conception of potential infinity. The concept of infinitely proceeding sequences generated by some calculation-rules is a typical infinite concept which can be found in Hilbert's finitary standpoint. However, Gentzen's finitism admits the infinitely proceeding sequences generated by free choices as well as ones generated by some rules. We conclude that in this respect he extended the concept of potential infinity which belongs to the finitist foundations of mathematics and this extension made his conception of potential infinity similar to intuitionists' one. Ryota Akiyoshi (Kyoto University): Brouwer's Proof of the Bar Induction Revisited In a series of papers, Brouwer had developed intuitionistic analysis, especially the theory of choice sequence. An important theorem called the ``fan theorem" is used in the development of intuitionistic analysis. The fan theorem was derived from another stronger theorem called the ``bar induction". Brouwer's argument for a justification of the bar induction contains a controversial assumption on canonical proofs of some formula. Constructive mathematicians have assumed the bar induction as axiom, hence the assumption has not been examined by them. On the other hand, Sundholm and van Atten claimed that the assumption should be regarded as transcendental one in the sense of Kant. They, however, did not give an explanation of why Brouwer needed such a problematic assumption. In this talk, we sketch a novel analysis of Brouwer's argument via infinitary proof theory. In particular, we point out that there is a close similarity between Brouwer's argument and Buchholz' the method of the $\Omega$-rule. By comparing these two arguments, we give a natural explanation of why Brouwer needed the assumption. If time is permitting, we list some open questions and problems. Sam Sanders (The University of Ghent) : Nonstandard Analysis: a New Way to Compute The system ERNA is a version of Nonstandard Analysis based on $I \Delta_0+EXP$. Recently, it was shown that many of the equivalences of $WKL_0$ over $RCA_0$ from Reverse Mathematics can be `pushed down' into ERNA's language, while preserving the equivalences, but at the price of replacing equality `=` by `$\approx$', i.e. equality up to infinitesimals from Nonstandard Analysis. We overview these results concerning ERNA and provide a possible explanation for the above similarity/robustness. In particular, we introduce `$\Omega$-invariance', a simple and elegant notion from Nonstandard Analysis meant to capture the notion of algorithm and Turing machine. Intuitively, an object is $\Omega$-invariant if it does not depend on the *choice* of infinitesimal used in its definition. We consider results regarding $\Omega$-invariance in classical and (time-permitting) constructive Reverse Mathematics. --------------------- Original Message Ends -------------------- -- mariko <yasugi(a)cc.kyoto-su.ac.jp>

Kobe Colloquium (Feb. 18, 2013)
by fuchino＠diamond.kobe-u.ac.jp 14 Feb '13

14 Feb '13

以下の要領でコロキウムを開催します．日時：2013年2月18日（月）15:10-16:40 場所：神戸大学自然科学総合研究棟3号館4階421室（プレゼンテーション室）講演者：Philip Welch (Univ. of Bristol) タイトル： Determinacy within Second Order Arithmetic Abstract: It was proven by H. Friedman in 1971 that the determinacy of two person perfect information games played on integers at the 5th level of the arithmetic hierarchy (so Sigma^0_5) would require the use of set theoretical axioms such as the Power Set Axiom. (This was improved by Martin to the 4th level.) Strategies for Sigma^0_k games for k =3D 1,2 were located in the Goedel L-hierachy by a folklore result (k=3D1) and Solovay (for k=3D2). We give a theorem on this kind for the last case left in the arithmetical hierarchy provable in analysis, thus for k=3D3. More recently Montalban and Shore have calculated the exact strength of determinacy provable in Second Order Number theory. We give some conjectures and a report on recent work that seeks to lift Montalban-Shore to the corresponding theory that includes a single measurable cardinal. -- best regards Saka\'e Fuchino (渕野昌) ------------------------------------------------------------------------- Kobe University Graduate School of System Informatics Rokko-dai 1-1, Nada, Kobe 657-8501 Japan e-mail: fuchino(a)diamond.kobe-u.ac.jp web page: http://kurt.scitec.kobe-u.ac.jp/~fuchino/ -------------------------------------------------------------------------

みなさま，国際ワークショップ ICE 2013 のお知らせです． - トピックは concurrency や coordination を軸に，verification, specification など多岐に渡ります．プログラミング言語理論や形式意味論などもスコープに入るはずです．（下をご覧ください） - フィレンツェの DisCoTec 併設です． - review の後，採否決定まで wiki による議論が行われます（レビュアー，著者，PC member 入り乱れて）．どうか投稿をご検討ください．それでは！蓮尾一郎東京大学コンピュータ科学専攻 http://www-mmm.is.s.u-tokyo.ac.jp/~ichiro/ ---------------------------------------------------------------------- [- Apologies for multiple copies -] ICE 2013 6th Interaction and Concurrency Experience June 6, 2013, Florence, Italy http://www.discotec.org/workshops/ice2013/ Satellite workshop of DisCoTec 2013 http://www.discotec.org === Highlights === - Invited talks: Davide Sangiorgi & Damien Pous - Innovative selection procedure - Special issue of Science of Computer Programming (http://www.journals.elsevier.com/science-of-computer-programming/) === Important Dates === 20 March 2013...................Full paper submission 21 March - 21 April 2013........Reviews, rebuttal, and PC discussion 24 April 2013...................Notification to authors 6 June 2013.....................ICE in Florence 15 Sept 2013....................Camera-ready for post-proceedings === Scope === Interaction and Concurrency Experiences (ICEs) is a series of international scientific meetings oriented to theoretical computer science researchers with special interest in models, verification, tools and programming primitives for complex interactions. The general scope of the venue includes theoretical and applied aspects of interactions and the synchronization mechanisms used among components of concurrent/distributed systems, related to several areas of computer science in the broad spectrum ranging from formal specification and analysis to studies inspired by emerging computational models. Topics of interest include, but are not limited to: - Process algebra and coordination: transformation, analysis and implementation - Models for distributed coordination and semantics - Techniques and tools for specification, analysis, verification of resilient interactions - Coinductive techniques for reactive systems - Languages, protocols and mechanisms for sound distributed coordination - Logics and types for interactions - Comparison among different coordination and/or execution models - Expressive power of coordination languages and execution models - Formal semantics of coordination languages - Formal verification of distributed coordinated architectures - Relations between different semantic models for coordination languages === Selection Procedure === Since its 1st edition in 2008, the distinguishing feature of ICE has been an innovative paper selection mechanism based on an interactive discussion amongst authors and PC members. During the review phase, each submitted paper is published on a Wiki and associated with a discussion forum. The discussion forum can be accessed by the authors of the paper and by all the PC members not in conflict with the paper. The forum is used by reviewers to ask questions and clarifications to the authors, allowing them to better explain all the aspects of their paper. The evaluation of the paper will keep into account not only the reviews, but also the outcome of the discussion. As witnessed by the past five editions of ICE, this procedure considerably improves the accuracy of the feedback from reviews, the fairness of the selection, the quality of camera-ready papers, and the discussion during the workshop. === The Public Wiki === After the notification, the accepted papers are published on a public forum, in order to initiate public discussions that will trigger and stimulate the scientific debate at the workshop. We believe that this will drive the workshop discussions and let prospective participants interact with each other much earlier than in more traditional events. === Submission Guidelines === We invite for three types of submissions: (1) Full Papers, (2) Short Papers, and (3) Brief Announcements of already Published Papers. Full and short papers to appear in the post-proceedings must report previously unpublished work and not be simultaneously submitted to other conferences/workshops with refereed proceedings. The ICE 2013 post-proceedings will be published in Electronic Proceedings in Theoretical Computer Science (http://eptcs.org/). In addition, we invite for brief announcements of already published results, should the authors feel like advertising their work and giving a talk. Brief announcements will not be part of the post-proceedings. Submissions must be made electronically in PDF format via EasyChair (http://www.easychair.org/conferences/?conf=ice2013). Full papers should not exceed 15 pages while short papers and brief announcements should not exceed 5 pages with the EPTCS style (http://style.eptcs.org/). Accepted (full and short) papers and brief announcements must be presented at the workshop by one of the authors. === Special Issue === Extended versions of the best full papers selected by the PC will be invited to appear in a special issue of the journal of Science of Computer Programming (http://www.journals.elsevier.com/science-of-computer-programming/ ). Such contributions will be regularly peer-reviewed according to the standard journal policy, but they will be handled in a shorter time than regular submissions. === Program Committee === Luca Aceto (Reykjavik University, Iceland) Simon Bliudze (EPFL, Switzerland) Laura Bocchi (University of Leicester, UK) Filippo Bonchi (CNRS, France) Roberto Bruni (University of Pisa, Italy) Marcello Bonsangue (Leiden University, The Netherlands) Ornela Dardha (University of Bologna/INRIA, Italy) Ichiro Hasuo (University of Tokyo, Japan) Tobias Heindel (CEA Saclay, France) Ludovic Henrio (CNRS, France) Clemens Kupke (University of Oxford, UK) Julien Lange (University of Leicester, UK) Antonia Lopes (University of Lisbon, Portugal) Giuliano Losa (EPFL, Switzerland) Claudio A.

CALL FOR PAPERS, 2nd International CONFERENCE on the HISTORY AND PHILOSOPHY OF COMPUTING (HaPoC 2013) 28th - 31st October 2013 Ecole Normale Superieure, Paris. with a special session on "Computing and the Arts" at Ecole Nationale Superieure des Arts Decoratifs http://hapoc2013.sciencesconf.org We are happy to announce that the 2nd International Conference on the History and Philosophy of Computing (HaPoC 2013) will take place from the 28th to the 31st of October 2013 at the Ecole Normale Superieure in Paris (France). The birth of the computing and its sciences has often been the topic of philosophical and historical reflection. The HaPoC-conferences have decided to bring together the historical and the philosophical viewpoints. They want to create an environment for a true interdisciplinary convergence around computer science, reenforcing research on the science(s) of computing and its history and stimulating a theoretical dialogue between these domains. To furter this dialogue HaPoC has chosen to have no parallel sessions. Our invited speakers are: Janet Abbate; Bernard Chazelle (tbc); Walter Dean; Nathan Ensmenger; Jean-Yves Girard; Barbara Liskov (tbc); Margit Rosen and Franck Varenne. HaPoC 2013 is the follow-up conference to HaPoC 2011 (Gent, Belgium). Please check out the website of HaPoC 2013 for more information on the conference: http://hapoc2013.sciencesconf.org For HaPoC 2013 we welcome contributions from logicians, philosophers and historians of computing as well as from philosophically aware computer scientists and mathematicians. Topics include but are not limited to: 1. Approaches to the notion of computing a. History and Philosophy of Computability b. History and Philosophy of Computation c. History and Philosophy of Programming d. History and Philosophy of the Computer 2. Applications and uses of Computing a. History and Epistemology of the use of Computing in the sciences b. Computing and the Arts : historical and conceptual issues c. Social, ethical and paedagogical aspects of Computing We cordially invite researchers working in a field relevant to the main topics of the conference to submit a short abstract of approximately 200 words and an extended abstract of at most a 1000 words (references included) to https://www.easychair.org/conferences/?conf=hapoc2 Abstracts must be written in English and anonymized. Please note that the format of uploaded files must be .pdf or .doc. The submission deadline is: April 30th, 2013 Best regards, the organisers, Maarten Bullynck (Paris 8 & SPHERE) Jean-Baptiste Joinet (Lyon 3, IRPhil & Cirphles) ------------------------------------------ Kazushige TERUI Research Institute for Mathematical Sciences, Kyoto University.

セミナーのお知らせ

08 Feb '13

皆様，東京工業大学の横山です．下記の要領でセミナーを行います．どうぞご参加ください．数理論理学セミナー (JSPS-FWO joint research seminar on mathematical logic) 日時：2月15日(金)14:30--18:00 (3講演) 場所：東京工業大学大岡山西８号館W棟11階 W1101セミナー室 14:30--15:30 Sam Sanders (Ghent University, Munich Center for Mathematical Philosophy of LMU) Title: Reuniting the antipodes: bringing together nonstandard analysis and constructive analysis Abstract: Recently, Sanders introduced an interpretation of Errett Bishop’s Constructive Analysis (BISH) inside a particular system of classical Nonstan- dard Analysis called NSA. The role of ‘algorithm’ is played by the notion Ω-invariance; Intuitively, an object is Ω-invariant if it does not depend on the choice of infinitesimal used in its definition. The role of ‘proof’ is played by the Transfer Principle of Nonstandard Analysis as follows: In the same way as the Brouwer-Heyting-Kolmogorov-interpretation is limited to provable formulas, we only consider formulas A such that A ↔ ∗A in NSA, i.e. formulas which ‘satisfy Transfer’. As NSA does not include non-trivial Transfer Principles, only some formulas A satisfy A ↔ ∗A. This interpretation from BISH into Nonstandard Analysis can be called ‘natural’ and ‘faithful’ in the following threefold way: (i) Non-constructive principles (LPO, LLPO, MP, etc.) are interpreted as Transfer Principles which are not available in the system NSA. (ii) The interpretation preserves the equivalences of Constructive Reverse Mathematics. (iii) The interpretation preserves the property that the BISH-notion of algo- rithm is weaker than that of recursive function. We discuss the interpretation from BISH into NSA, and related topics. 15:45--16:45 Tin Lok Wong (Ghent University) Title: Countable numbers in a model of arithmetic: a survey Abstract: A *countable number* in a model M of Peano arithmetic is a number that has countably many predecessors in M. I will survey some results about these countable numbers as an initial segment of the model M. Most of this talk will be accessible to everyone who has some basic knowledge in cardinals and in the Completeness Theorem for first-order logic. 17:00--18:00 Florian Pelupessy (Ghent University) Title: Unprovable theorems. Abstract: We will provide a gentle introduction to some interesting natural theorems which are not provable in Peano Arithmetic. These theorems are natural in the sense that they are similar to ordinary theorems from the mathematics literature. We will discuss two important methods of showing unprovability for these theorems, one using results from proof theory and one from model theory. ------ 問い合わせ先：横山　啓太（東京工業大学） yokoyama.k.ai(a)m.titech.ac.jp 横山啓太 -- Keita Yokoyama yokoyama.k.ai(a)m.titech.ac.jp

A typical approach to ICC is to consider a computational model (in finite model theory, recursion theory, term rewriting, functional programming, etc.) and propose a　*qualitative* criterion/certificate for a program in the model to be executed within a given time/space bound (e.g. polynomial time). Here we are particularly interested in higher order functional programming languages, which are often modeled by lambda calculus. It is then types that give a criterion/certificate for the resource bound. Because of the Curry-Howard correspondence, it is also linked to constructive logics. Linear logic plays a prominent role in this context. The purpose of this talk is to give a general overview of the type-theoretic approaches to ICC. It will be neither comprehensive nor detailed. I will just review some nice ideas in the past development, and discuss their future possibilities from my very personal (and sometimes critical) point of view. The topics will be chosen from the following list: - safe recursion in higher order - linearity and various modalities - arithmetic systems based on ICC - realizability semantics - denotational semantics - time-space tradeoff in lambda calculus ---- 15:10-16:10 Sebastian Müller (Charles University) Short Refutations of Random 3CNF in TC0-Frege (joint work with Iddo Tzameret) A classical result by Chvatal and Szemeredi states that with high probability, a given random 3CNF is unsatisfiable, if the clause-to-variable ratio is larger than 8 ln(2). On the other hand, on almost all unsatisfiable random 3CNF with a clause-to-variable ratio of less than n^0,5 (where n is the number of variables) Resolution fails to witness that unsatisfiability efficiently (due to Ben-sasson and Wigderson). On the other hand, Feige, Kim and Ofek constructed a witness for unsatisfiability that is polynomial-time constructable and works for random 3CNF with a clause-to-variable ratio above n^0,4. Iddo Tzameret and me formalized this witness in a weak bounded arithmetic theory called VTC^0. I will explain this result and sketch the main steps of the proof and later eloborate on the consequences for propositional proof system. As a direct consequence we receive efficient refutability of such formulas in TC^0-Frege proof systems and, with the above, a separation between such systems and Resolution on a random, dense set. ---- 16:30-17:30 Martin Ziegler (TU Darmstadt) Real Benefit of Promises and Advice (joint work with Ulrike Brandt and Klaus Ambos-Spies) Promises are a standard way to formalize partial algorithms; and advice quantifies nonuniformity. For decision problems, the latter it is captured in common complexity classes such as P/poly, that is, with advice growing in size with that of the input. We advertise constant-size advice and explore its theoretical impact on the complexity of classification problems – a natural generalization of promise problems -- and on real functions and operators. Specifically we exhibit problems that, without any advice, are decidable/computable but of high complexity while, with (each increase in the permitted size of) advice, (gradually) drop down to polynomial-time. ---- 18:00- Dinner (Please register on the webpage if you are coming to the dinner.)

Prof. Helmut Schwichtenberg Lecture at NII Logic Seminar
by Makoto Tatsuta 08 Feb '13

08 Feb '13

Prof. Helmut Schwichtenberg Lecture at NII Logic Seminar Date: February 21, 2013, 14:00--16:00 Place: National Institute of Informatics, Lecture Room 1208 (12th floor) 場所: 国立情報学研究所 12階 1208室 (半蔵門線,都営地下鉄三田線・新宿線神保町駅または東西線竹橋駅より徒歩5分) (地図 http://www.nii.ac.jp/about/access/) Speaker: Prof. Helmut Schwichtenberg (Ludwig Maximilian University of Munich) Title: Proofs and computations with infinite data Abstract: Ulrich Berger and Monika Seisenberger recently studied extraction from proofs involving (only) abstract reals. They considered a proof using coinduction of the proposition that any two reals in [-1,1] have their average in the same interval, and informally extract a Haskell program working with stream representations of reals. We report on a formalization of this proof, and a machine-extraction of its computational content, in the Minlog proof assistant. This required an extension of this system to also take coinduction into account. The underlying formal system is a theory TCF of computable functionals. It is similar to Heyting arithmetic in all finite types, but with the Scott/Ershov partial continuous functionals as the domain of quantifiers. TCF has free type, predicate and function variables, to allow for abstract developments (groups, fields, real analysis). The underlying inference machinery is minimal logic (implication, universal quantification plus inductively and coinductively defined predicates). Computable functionals (of finite type, with free algebras at ground types) are given by their defining equations. Since the logic is constructive, program extraction by means of a realizability interpretation is possible and a soundness theorem holds. 問合せ先: 龍田真 (国立情報学研究所) e-mail: tatsuta(a)nii.ac.jp http://research.nii.ac.jp/~tatsuta

Dr. Sam Sanders Lecture at NII Logic Seminar Date: February 13, 2013, 13:30--15:30 Place: National Institute of Informatics, Lecture Room 1904 (19th floor) 場所: 国立情報学研究所 19階 1904室 (半蔵門線,都営地下鉄三田線・新宿線神保町駅または東西線竹橋駅より徒歩5分) (地図 http://www.nii.ac.jp/about/access/) Speaker: Dr. Sam Sanders (University of Ghent) Title: Reuniting the antipodes: Bringing together Nonstandard Analysis and Constructive Analysis Abstract: Constructive Analysis (aka BISH) was introduced by Errett Bishop as a redevelopment of Mathematics with a focus on computational content. As such, BISH is based on the BHK (Brouwer-Heyting-Kolmogorov) interpretation of logic, where the notions of `proof' and `algorithm' are central. Constructive Reverse Mathematics (CRM) is a spin-off from Harvey Friedman's `Reverse Mathematics' program where the base theory is based on BISH. In this talk, we introduce an interpretation of BISH in classical Nonstandard Analysis. The role of `proof' in this interpretation is played by the Transfer Principle of Nonstandard Analysis. The role of `algorithm' is played by `$\Omega$-invariance'. Intuitively, an object is $\Omega$-invariant if it does not depend on the *choice* of infinitesimal used in its definition. Using this new interpretation, we obtain many of the well-known results form CRM. In particular, all non-constructive principles (like LPO, LLPO, MP, etc) are interpreted as Transfer Principles, which are not available in our nonstandard base theory. Finally, the interpretation preserves the property that not all $\Delta_1$-formulas are decidable in BISH. We discuss applications in (Homotopy) Type Theory. 問合せ先: 龍田真 (国立情報学研究所) e-mail: tatsuta(a)nii.ac.jp

However, a special weak form of it (Ramsey Theorem for Pairs) has been a hot topic in Recursion Theory and Reverse Mathematics. In this talk I will give a survey on some recent progresses related to combinatoric principles weaker than Ramsey's Theorem for Pairs. In particular, I will speak about some results obtained by Chitat Chong, Ted Slaman and me on the first order and second order arithmetical consequences of Ramsey Theorem for Pairs. 問合せ先: 龍田真 (国立情報学研究所) e-mail: tatsuta(a)nii.ac.jp http://research.nii.ac.jp/~tatsuta

Kobe Colloquium (Feb 6, 2013, Pelupessy)
by Makoto Kikuchi 04 Feb '13

04 Feb '13

Kobe Colloquium on Logic, Statistics and Informatics 以下の要領でコロキウムを開催します。日時：2013年2月6日（水）15:10-16:40 場所：神戸大学自然科学総合研究棟3号館4階421室（プレゼンテーション室）講演者：Florian Pelupessy (Ghent) ======================================================================== 題目：Connecting the provable with the unprovable アブストラクト： Since Gödels famous incompleteness theorems it is well known that there exist theorems which are not provable in Peano Arithmetic. In the last decades of the last century many mathematically interesting examples of such unprovable statements emerged, for example: the Paris-Harrington theorem, the Kanamori-McAloon theorem, Kruskal's tree theorem, Hydra battles and Goodstein sequences. In these theorems it is possible to insert a parameter function, where the resulting theorem variant with constant parameter is provable, but the variant with as parameter the identity function is unprovable. An obvious question in these cases is at which threshold between those functions (ordered by eventual domination) the resulting theorem changes from provable to unprovable: the phase transition for provability of the theorem. We study these phase transitions with the goal of better understanding unprovability. We will be examining the transition results for three Ramsey theorem variants: Friedman's adjacent Ramsey theorem, the Paris-Harrington theorem and the Kanamori-McAloon theorem. For these theorems it is possible to show a deep connection between lower/upper bound estimates for the variants with constant parameter values and the threshold values for the parametrised theorems. This shows an influence of mathematics which is provable at a level slightly stronger than exponential function arithmetic on provabiltiy at the level of Peano Arithmetic. ======================================================================== 交通：阪急六甲駅またはJR六甲道駅から神戸市バス36系統「鶴甲団地」行きに乗車，「神大本部工学部前」停留所下車，徒歩すぐ． http://www.kobe-u.ac.jp/info/access/rokko/rokkodai-dai2.htm 連絡先：菊池誠　mkikuchi(a)kobe-u.ac.jp

Eighth NII Type Theory Workshop

Eighth NII Type Theory Workshop Date: February 6, 2013, 10:40--16:50 Place: National Institute of Informatics, Room 1904 (19th floor) 場所: 国立情報学研究所 19階 1904室 (半蔵門線,都営地下鉄三田線・新宿線神保町駅または東西線竹橋駅より徒歩5分) (地図 http://www.nii.ac.jp/about/access/) Program: 10:40--11:20 Toshihiko Uchida (The Graduate University for Advanced Studies) Title: A Partial Translation from lambda U to lambda 2 11:20--12:00 Daisuke Kimura (National Institute of Informatics) Title: Linear Pure Type Systems 12:00--14:00 Lunch Break 14:00--14:40 Kazuyuki ASADA (National Institute of Informatics) Title: Curry-Howard Correspondence between Dialectica Interpretation and Bidirectional Transformation 14:40--15:20 Makoto Tatsuta (National Institute of Informatics) Title: Dual Calculus with Inductive and Coinductive Types 15:20--15:50 Tea Break 15:50--16:50 Stefano Berardi (Torino University) Title: A Curry-Howard result for various subclassical logics Abstracts: ---------------------------------------------------------------------- Toshihiko Uchida (The Graduate University for Advanced Studies) Title: A Partial Translation from lambda U to lambda 2 Abstract: Girard showed that every type of sort * (i.e., proposition) is inhabited in lambda U. Barendregt state without proof that every type of sort Box (i.e., domain) is also inhabited in the system. In this talk, we show that the second statement is not the case by giving a partial translation from lambda U to lambda 2. ---------------------------------------------------------------------- Daisuke Kimura (National Institute of Informatics) Title: Linear Pure Type Systems Abstract: This talk proposes a linear variant of Pure Type Systems (PTSs), called linear pure type systems (LPTSs). It is a general framework, which provides a uniform way to treat various linear type systems that have the features of linear logic. We first introduce a subframework of LPTSs, called multiplicative linear pure type systems (MLPTSs), in which only variables that linearly occur are abstracted. All MLPTSs are consistent and satisfy strong normalization. However their expressive power is rather weak. We then give LPTSs by extending MLPTSs with exponentials. Each PTS can be embedded into a LPTS. We also show the equivalence of strong normalizability of PTSs and LPTSs by giving mutual translations between them. ---------------------------------------------------------------------- Kazuyuki ASADA (National Institute of Informatics) Title: Curry-Howard Correspondence between Dialectica Interpretation and Bidirectional Transformation Abstract: We give Curry-Howard style correspondence between (propositional logic part of) Dialectica interpretation and bidirectional transformation. Dialectica interpretation was introduced by Godel to show relative consistency of Heyting Arithmetic to System T. Independently, bidirectional transformation arose in database community for automatic view-update problem, and recently have been studied in programming language community to formulate languages for bidirectional transformations. A bidirectional transformation consists of a pair of forward ("usual") transformation and a backward ("inverse") transformation, and we usually assume that they satisfy some standard axioms called GetPut law and PutGet law. We show GetPut law naturally fits the above correspondence to Dialectica interpretation, and this gives a way of extending a language for bidirectional transformations with GetPut law. Then we modify the above scheme for PutGet law and the combination of GetPut and PutGet laws. We also show that Paiva's variant of Dialectica model, GC, corresponds to the category for inverse computation. Then for the result by Paiva that the original Dialectica category is the coKleisli category of some comonad on GC, we give similar result for PutGet law, and we utilize this to investigate further categorical structures of these models. Also we see that a kind of Diller-Nahm variant of Dialectica interpretation corresponds to backward-partial bidirectional transformation. ---------------------------------------------------------------------- Makoto Tatsuta (National Institute of Informatics) Title: Dual Calculus with Inductive and Coinductive Types Abstract: This talk gives an extension of Dual Calculus by introducing inductive types and coinductive types. The same duality as Dual Calculus is shown to hold in the new system, that is, this talk presents its involution for the new system and proves that it preserves both typing and reduction. The duality between inductive types and coinductive types is shown by the existence of the involution that maps an inductive type and a coinductive type to each other. The strong normalization in this system is also proved. First, strong normalization in second-order Dual Calculus is shown by translating it into second-order symmetric lambda calculus. Next, strong normalization in Dual Calculus with inductive and coinductive types is proved by translating it into second-order Dual Calculus. This is a joint work with Daisuke Kimura. ---------------------------------------------------------------------- Stefano Berardi (Torino University) Title: A Curry-Howard result for various subclassical logics Abstract: We introduce games with Sequential Backtracking as a model for various sub-classical logic that have implication as a primitive connective. We define a one-sided version of the logical systems, whose proofs have a tree isomorphism (a kind of ``Curry Howard'' isomorphism) with respect to the winning strategies of the game semantics. We use this correspondence to interpret various classical proofs as learning algorithms. ---------------------------------------------------------------------- 問合せ先　龍田 (tatsuta(a)nii.ac.jp)

We deﬁne a game theoretic semantics, which can be regarded as a version of Austin semantics. Graham E. Leigh (University of Oxford) title: Global reflection and theories of truth Abstract: This talk explores the relationship between the global reflection principle ("If A is provable, A is true") and its arithmetic cousins ("If A is provable then A"). I will provide a proof-theoretic analysis of a number of axiomatic theories of truth expanded by transfinite hierarchies of reflection principles. Katsuhiko Sano (School of Information Science, Japan Advanced Institute of Science and Technology) title: What is the corresponding first-order logic to coalgebraic modal logic? Abstract: It is well-known that modal logic over Kripke models can be regarded as the bisimulation-invariant fragment of first-order logic, where the notion of bisimulation tells us when given two Kripke models are `similar' with each other. This is called Van Benthem's characterization theorem. The main aim of this talk is to propose a corresponding first-order syntax with Van Benthem-style characterization to coalgebraic modal logic, a uniform framework to cover modal logic over Kripke models, modal logic over neighborhood models, graded modal logic, probabilistic modal logic, etc. This talk focuses on a conceptual background to explain our strategy of finding a corresponding FO syntax for coalgebraic modal logic. A key idea consists in Arthur Prior's early idea of hybrid logic (esp. modal operators for pointed truth) and C. C. Chang's FO syntax for neighborhood models. This talk is based on a joint work with Dirk Pattinson (ANU), Tadeusz Litak (Friedrich-Alexander University of Erlangen and Nuremberg (FAU)), and Lutz Schroeder (FAU). Leon Horsten (University of Bristol) title: One hundred years of semantic paradox Abstract: This article contains an overview of the main problems, themes and theories relating to the semantic paradoxes in the twentieth century. From this historical overview I tentatively draw some lessons about the way in which the field may evolve in the next decade.

Speaker: Prof. Randy Goebel (department of Computing Science at the University of Alberta, in Edmkonton, Alberta, Canada) He is also vice president of the innovates Centre of Research Excellence (iCORE) at Alberta Innovates Technology Futures (AITF), chair of the Alberta Innovates Academy, and principle investigator in the Alberta Innovates Centre for Machine Learning. He received the B.Sc. (Computer Science), M.Sc. (Computing Science), and Ph.D. (Computer Science) from the Universities of Regina, Alberta, and British Columbia, respectively. At AITF, Randy is in charge of reshaping research investments (graduate student scholarships, research chairs, research centres). His research interests include applications of machine learning to systems biology, visualization, and web mining, as well as work on natural language processing, web semantics, and belief revision. Randy has experience working on industrial research projects in crew scheduling, pipeline scheduling, and steel mill scheduling, as well as scheduling and optimization projects for the energy industry in Alberta. Randy has held appointments at the University of Waterloo, University of Tokyo, Multimedia University (Malaysia), Hokkaido University (Sapporo), and has had research collaborations with DFKI (German Research Centre for Artificial Intelligence), NICTA (National ICT Australia), RWC (Real World Computing project, Japan), ICOT (Institute for New Generation Computing, Japan), NII (National Institute for Informatics, Tokyo), and is actively involved in academic and industrial collaborative research projects in Canada, Australia, Europe, and China. Abstract: The modern discipline of computer science has many facets, but what has clearly emerged in the last decade are three themes based on 1) rapidly accumulating volumes of data, 2) inter- and cross-disciplinary application of computer science to all scientific disciplines, and 3) a renewed interest in the semantics of complex information models, spanning a spectrum from semantic web, natural language, to multi-scale systems biology. This series of four lectures will attempt to knit together these three themes, by presenting the ideas that have emerged in their support: the rapid development and extension of machine learning theory and methods to help make sense of accumulating volumes of data, the application of computer science to nearly all scientific disciplines, especially those whose progress now necessarily relies on the management and interpretation of large data, and finally, the revival of a focus on semantics of information models based on data. Outline: Lecture 1: Connecting Advice Taking and Big Data Lecture 2: Structured inference and incomplete information Lecture 3: Natural Language Processing: Compressing Data to Models Lecture 4: Hypothesis Management with Symbols and Pictures Place: Lecture room 2010, 20th floor, National Institute of Informatics Date: 13:30pm-15:00pm, February 12, 20, 26, March 1, 2013 Lecture 1 Connecting Advice Taking and Big Data Tuesday, February 12, 2013, 13:30 - 15:00 A fundamental premise of Artificial Intelligence (AI) is the ability for a computer program to improve its behaviour by taking advice. Incremental accumulation of advice or knowledge has never been easier than today, when the rate of data capture is higher than ever before, and the management of big data and deployment of machine learning are coupled to help manage the transition from data to knowledge. This lecture uses simple technical concepts from nearly sixty years of AI, to identify some of the research challenges of managing big data, and exploiting knowledge emergent from big data. The goal is to find some important research priorities based on the motivation of the Advice Taker, and the current state of big data management and machine learning. Lecture 2 Structured inference and incomplete information Wednesday. February. 20, 13:30 - 15:00 If the foundation of Artificial Intelligence (AI) is the accumulation and use of knowledge, then a necessary stop is the structuring knowledge to be able to make inferences. The organization structures required to facilitate inference now span a broad spectrum of mathematical methods, including everything from simple propositional logic to sophisticated statistical and probabilistic inference. The two foundational components of computational inference are semantics of formal reasoning, and the development of reasoning methods to deal with incomplete information. This lecture reviews the foundational components of semantics and reasoning systems, including the development of goal-oriented reasoning based on abductive reasoning, the connection between logical and probabilistic systems, and especially how the architecture of reasoning systems can provide the basis for managing hypotheses in the face of incomplete information. Lecture 3 Natural Language Processing: Compressing Data to Models Tuesday. February. 26, 13:30 - 15:00 The problem of machine processing of natural language (NLP) has long been a research focus of artificial intelligence. This is partly because the use of natural language is easily conceived as a cognitive task requiring human-like intelligence. It is also because the rational structures for computer interpretation of language require the full suite of computational tools developed over the last hundred years (grammar, dictionaries, logic, parsing, inference, and context management). Most of the recent practical advances in NLP have arisen in the context of simple machine learning applied to large language corpora, to induce fragments of language models that provide the basis for interpretive and generative manipulation of language. These largely statistical models are arisen in what has been called the "pendulum swing" of NLP, in which statistical models have recently dominated those based on structural linguistics. In this lecture, we look at the concept of noisy corpora and their role in language models, including some interesting alternative sources of data for building language models. The applications range from complex language summary to the information extraction from medical, legal, and historical documents. Lecture 4 Hypothesis Management with Symbols and Pictures Friday. March. 1, 13:30 - 15:00 The current suite of Artificial Intelligence (AI) tools has provided a basis for sophisticated human-computer interfaces based on more than typing in language. In fact, one can develop multi-level representations that provide the basis for direct manipulation of visualizations. By constraining the repertoire of direct manipulations, one can enrich human computer interaction so that both humans and machines can understand and exploit visual interaction. This lecture shows how such direction manipulation requires a large repertoire of formal reasoning methods, and provides the sketch of formal framework and the problems arising in its development.

＜重複してお受け取りの方はご容赦ください＞皆様：中央大学の只木と申します。中央大学研究開発機構では、来週19日土曜日、ニュージーランド研究者Cristian S. Calude氏（オークランド大学）およびElena Calude氏（マッセイ大学）をお招きし、下記要領で講演会を開催します。皆様、奮ってご参加下さい。 ---------------------------------- 只木孝太郎 (Kohtaro Tadaki) 中央大学研究開発機構〒112-8551 東京都文京区春日1-13-27 E-mail: tadaki(a)kc.chuo-u.ac.jp WWW: http://www2.odn.ne.jp/tadaki/ ---------------------------------------------------------- Cristian S. Calude氏、Elena Calude氏講演会 ◆日時： 2013年1月19日（土）15時00分〜 17時30分 ◆場所：中央大学後楽園キャンパス 5号館1階 5138号室（下記参照） ◆参加申込：不要 ---------------------------------------------------------- [ 講演内容 ] ◆15時00分〜16時00分講演題目：The complexity of mathematical problems 講演者：Cristian S. Calude (University of Auckland, NZ) and Elena Calude (Massey University, NZ) 講演要旨： Evaluating (or even guessing) the degree of complexity of an open problem, conjecture or mathematically proven statement is not an easy task not only for beginners, but also for the most experienced mathematicians. Is there a (uniform) method to evaluate, in some objective way, the difficulty of a mathematical statement or problem? The question is not trivial because mathematical problems can be so diverse. But, is there any indication that all, or most, or even a large part of mathematical problems have a kind of "commonality" allowing a uniform evaluation of their complexity? How could one compare a problem in number theory with a problem in complex analysis, a problem in algebraic topology or a theorem in dynamical systems? Surprisingly enough, such "commonalities" do exist for many mathematical problems. One of them is based on the possibility of expressing the problem in terms of (very) simple programs reducible to a (natural) question in theoretical computer science, the so-called "halting problem". A more general "commonality" can be discovered using the inductive type of computation, a computation more general the Turing computability. As a consequence, uniform approaches for evaluating the complexity of a large class of mathematical problems/conjectures/statements can be, and have been, developed. This talks reviews current progress and some open problems. ◆16時30分〜17時30分講演題目： The Kochen-Specker theorem and quantum randomness 講演者： Cristian S. Calude (University of Auckland, NZ) 講演要旨： The Kochen-Specker theorem shows the impossibility for a hidden variable theory to consistently assign values to certain (finite) sets of observables in a way that is noncontextual and consistent with quantum mechanics. If we require noncontextuality, the consequence is that many observables must not have pre-existing definite values. However, the Kochen-Specker theorem does not allow one to determine which observables must be value indefinite. In this talk we present an improvement on the Kochen-Specker theorem which allows one to actually locate observables which are provably value indefinite. Various technical and subtle aspects relating to this formal proof and its connection to quantum mechanics are discussed. This result is then utilized for the proposal and certification of a dichotomic quantum random number generator operating in a three-dimensional Hilbert space. ------------------------------------------------------------ 会場への道順： [中央大学後楽園キャンパスへのアクセスガイド] http://www.chuo-u.ac.jp/chuo-u/access/index_j.html http://www.chuo-u.ac.jp/chuo-u/access/access_korakuen_j.html [中央大学後楽園キャンパスマップ] http://www.chuo-u.ac.jp/chuo-u/campusmap/korakuen_j.html ------------------------------------------------------------

HAS 2013: Deadline Extended
by Ichiro Hasuo 06 Jan '13

06 Jan '13

みなさま，東京大学の蓮尾です．あけましておめでとうございます．以前お知らせした ETAPS 併設ワークショップの HAS，締切が 1/21 に延長になりました．Post-proceeding ですので，論文の preliminary version でも大歓迎，とのことです．ご投稿を検討いただければ幸いです．どうかよろしくお願いいたします．それでは！蓮尾一郎 http://www-mmm.is.s.u-tokyo.ac.jp/~ichiro/ =========================== [Apologies for multiple copies] [Please note: submission deadline extended to January, 12] ************************************************************************************************************ ********* CALL FOR PAPERS Third Workshop on Hybrid Autonomous Systems (HAS 2013) A satellite event of European Joint Conferences on Theory and Practice of Software, ETAPS 2013 March 17, 2013, Rome, Italy http://www2.warwick.ac.uk/fac/sci/maths/people/staff/bujorianu/has2013/ ************************************************************************************************************ ********* SCOPE: The interest on autonomous systems is increasing both in industry and academia. Such systems must operate with limited human intervention in a changing environment and must be able to compensate for significant system failures without external intervention. The hybrid discrete-continuous models constitute appropriate models of autonomous systems . Hybrid systems have behaviours characterised by the interaction between continuous and discrete dynamics and research in the area is driven by several school of thoughts. One approach is mainly focussed on applications to automation systems and the models and methods are centred on the concept of hybrid automaton (deterministic or probabilistic). A distinct school of thought interprets hybrid systems as control systems with regime change. Such systems are highly adaptive and suitable for modelling autonomic behaviours. The most prominent models of this approach are the stochastic hybrid systems and the mixed logical and dynamical systems. There is a clear research opportunity to combine these approaches for developing models, methods, techniques, methodologies, tools and environments for autonomous systems engineering. This workshop brings together researchers interested in all aspects of autonomy and resilience of hybrid systems. TOPICS: Topics include (but are not limited to): Ø new modelling paradigms for autonomous systems; Ø verification and safety certification techniques; Ø modelling, analysis and control of hybrid systems; Ø uncertainty and stochastic modelling; Ø multi-agent systems; Ø algebraic and categorical methods; Ø interaction between hybrid modelling and complexity science; Ø reports on case studies and practical experiments; Ø autonomous systems in natural science (e.g. from biology, ecology, climate).

It is easily accessible via two airports: the main Chopin Airport, used by most international carriers, and the recently open Warsaw Modlin Airport (30 minutes away by rail), used by budget airlines. -- SATELLITE WORKSHOPS -- CALCO 2013 will be preceded by the CALCO Early Ideas Workshop, chaired by Monika Seisenberger (Swansea University). The workshop is dedicated to presentation of work in progress and original research proposals. PhD students and young researchers are particularly encouraged to contribute. Attendance at the workshop is open to all - it is anticipated that many CALCO conference participants will want to attend the CALCO Early Ideas workshop (and vice versa). A workshop dedicated to tools based on algebraic and/or coalgebraic principles, CALCO Tools, will be held alongside the main conference, chaired by Lutz Schr??der (Friedrich Alexander Universit??t Erlangen-N??rnberg). Papers of this workshop will be included in the CALCO proceedings. -- CALCO Early Ideas Overview -- The CALCO Early Ideas Workshop invites submissions on the same topics as the CALCO conference: reporting results of theoretical work on the mathematics of algebras and coalgebras, the way these results can support methods and techniques for software development, as well as experience with the transfer of the resulting technologies into industrial practice. The list of topics of particular interest is shown on the main CALCO 2013 page. CALCO Early Ideas presentations will be selected according to originality, significance, and general interest, on the basis of submitted 2-page short contributions. It can be work in progress, a summary of work submitted to a conference or workshop elsewhere, or work that in some other way might be interesting to the CALCO audience. A booklet with the accepted short contributions will be available at the workshop. Submissions will be handled via EasyChair https://www.easychair.org/conferences/?conf=calcoearlyideas2013 The use of LNCS style is strongly encouraged. After the workshop, authors will have the opportunity to submit a full 10-15 page paper on the same topic. The reviewing will be carried out by the CALCO Early Ideas PC, with the support of the CALCO PC. The volume of selected papers will be available online. Authors will retain copyright, and are also encouraged to disseminate the results by subsequent publication elsewhere. http://coalg.org/calco13/workshops.html#ei -- CALCO Early Ideas Dates -- 2-page short contribution submission: May 27, 2013 Notification for short contribution: June 24, 2013 Final short contribution due: July 15, 2013 CALCO Early Idead Workshop: September 2, 2013 10-15 page paper submission: October 15, 2013 Notification for paper: December 15, 2013 Final paper version due: January 15, 2014 -- CALCO Early Ideas Program Committee -- Bartek Klin, University of Warsaw, Poland John Power, University of Bath, UK Monika Seisenberger, Swansea University, UK (chair) -- CALCO-Tools Overview -- CALCO-Tools will take place on the same dates as the main CALCO conference, with no overlap between the technical programmes of the two events. Topics of interest include systems, prototypes, and tools developed specifically for the design, checking, execution, and verification of (co)algebraic specifications, but also tools targeting different application domains while making core or interesting use of (co)algebraic techniques. Tool submissions should not exceed 5 pages in LNCS format. The accepted tool papers will be included in the final proceedings of the conference. The tools should be made available on the web at the time of submission.

25 Dec '12

# 重複の場合はご容赦ください．神戸大学の田村と申します．メーリングリストをお借りして，来年7月にヘルシンキで開催されます SAT 2013 の Call For Papers をお送りします． -- 田村直之 (tamura(a)kobe-u.ac.jp) 神戸大学情報基盤センター〒657-8501 神戸市灘区六甲台町1-1 Phone: 078-803-5364, Fax: 078-803-5375 http://bach.istc.kobe-u.ac.jp/tamura-jp.html COPRIS+SCALA+CSP=SOLVER ------------------------------------------------------------------------- 1st CALL FOR PAPERS Sixteenth International Conference on THEORY AND APPLICATIONS OF SATISFIABILITY TESTING --- SAT 2013 --- Helsinki, Finland, July 8-12, 2013 http://sat2013.cs.helsinki.fi/ Abstract submission deadline: February 1, 2013 Paper submission deadline: February 8, 2013 ------------------------------------------------------------------------- The International Conference on Theory and Applications of Satisfiability Testing (SAT) is the primary annual meeting for researchers studying the theory and applications of the propositional satisfiability problem, broadly construed. Besides plain propositional satisfiability, it includes Boolean optimization (including MaxSAT and Pseudo-Boolean (PB) constraints), Quantified Boolean Formulas (QBF), Satisfiability Modulo Theories (SMT), and Constraint Programming (CP) for problems with clear connections to Boolean-level reasoning. Many hard combinatorial problems can be encoded as SAT instances, in the broad sense mentioned above, including problems in formal verification (hardware and software), artificial intelligence, and operations research. More recently, biology, cryptology, data mining, machine learning, and mathematics have been added to the growing list. The SAT conference aims to further advance the field by soliciting original theoretical and practical contributions in these areas with a clear connection to satisfiability. SAT 2013 takes place in Helsinki, the capital of Finland. Helsinki is a vibrant Scandinavian and international city with a lot to offer to visitors. SAT 2013 takes place during the main summer season, allowing one to experience the whitenights during which the sun almost never sets. IMPORTANT DATES =============== (Follow http://sat2013.cs.helsinki.fi/ for updates.) February 1, 2013: Abstract Submission February 8, 2013: Paper Submission March 18, 2013 (approx.): Response from Authors begins, lasts 72 hours April 3, 2013: Acceptance Notifications April 22, 2013: Final Camera-Ready Versions July 8, 2013: Workshops begin July 9-12, 2013: Main Conference SCOPE ===== SAT 2013 welcomes scientific contributions addressing different aspects of the satisfiability problem. interpreted in a broad sense. Domains include MaxSAT and Pseudo-Boolean (PB) constraints, Quantified Boolean Formulae (QBF), Satisfiability Modulo Theories (SMT), Constraint Satisfaction Problems (CSP). Topics include (but are not restricted to) Theoretical advances (including exact algorithms, proof complexity, and other complexity issues); Practical search algorithms; Knowledge compilation; Implementation-level details of SAT solving tools and SAT-based systems; Problem encodings and reformulations; Applications (including both novel applications domains and improvements to existing approaches); Case studies and reports on insightful findings based on rigorous experimentation. OUT OF SCOPE ============ Papers claiming to resolve a major long-standing open theoretical question in mathematics or computer science (such as those for which a Millennium Prize is offered, see http://www.claymath.org/millennium) are outside the scope of the conference because there is insufficient time in the schedule to referee such papers; instead, such papers should be submitted to an appropriate technical journal. SUBMISSIONS =========== Submissions to SAT 2013 are solicited in three paper categories, describing original contributions: REGULAR PAPERS (9 to 15 pages, excluding references) Regular papers should contain original research, with sufficient detail to assess the merits and relevance of the contribution. For papers reporting experimental results, authors are strongly encouraged to make their data and implementations available with their submission. Submissions reporting on case studies are also encouraged, and should describe details, weaknesses, and strengths in sufficient depth. SHORT PAPERS (up to 8 pages, excluding references) The same evaluation criteria apply to short papers as to regular papers. They will be reviewed to the same standards of quality as regular papers, but will naturally contain less quantity of new material. Short papers will have the same status as regular papers and be eligible for the same awards (to be announced later). TOOL PAPERS (up to 6 pages, excluding references) A tool paper should describe the implemented tool and its novel features. Here "tools" are interpreted in a broad sense, including descriptions of implementations of core SAT solving techniques (solvers, preprocessors, etc.), systems exploiting SAT solvers or their extensions for solving interesting problem domains, etc. A demonstration is expected to accompany a tool presentation. Papers describing tools that have already been presented previously are expected to contain significant and clear enhancements to the tool. The software for the tool should be made publicly available, for accepted tool papers, and should at least be available to reviewers for evaluation during the review period. Evaluation criteria will include (but not be limited to) accurate documentation, usability, and potential for furthering the state of the art. For the latter criterion, availability of source code will be a significant factor. This is an evolving category, and technical issues involving software availability should be discussed with the program chairs. Be sure to check the conference web page for updates on this category. Papers describing unpublished tool-related work, providing details on a system and the novel algorithms it implements, as well as an experimental evaluation of the system's performance, can also be submitted as regular papers. For all paper categories, the page limits stated above do not include references, but do include all other material intended to appear in the conference proceedings. An additional technical appendix may be included, but it must be clearly labeled as supplementary material and may or may not be examined during review based of the considerations of individual reviewers. The appendix may contain detailed proofs, examples, descriptions of publicly available software related to the submission, or other information that does not fit the page limit. However, the appendix will not be included in the conference proceedings. The main contributions should be made accessible within the page limits, without having to rely on the appendix. Submissions should not be under review elsewhere nor be submitted elsewhere while under review for SAT 2013, and should not consist of previously published material. Submissions must use the Springer LNCS style without modifications, and must be written in English.

Topics of interest include, but are not limited to: - Formalisms for modeling hardware, software and embedded systems - Specification and verification of finite-state, infinite-state and parameterized system - Program analysis and software verification - Analysis and verification of hardware circuits, systems-on-chip and embedded systems - Analysis of real-time, hybrid, priced/weighted and probabilistic systems - Deductive, algorithmic, compositional and abstraction/refinement techniques for analysis and verification - Analytical techniques for safety, security, and dependability - Testing and runtime analysis based on verification technology - Analysis and verification of parallel and concurrent hardware/software systems - Verification in industrial practice - Applications and case studies Theory papers should preferably be motivated by practical problems, and applications should be based on sound theory and should solve problems of practical interest. SUBMISSION Submissions are invited in two categories: regular research papers and tool papers. Submitted papers must present original and unpublished work, and must not be concurrently submitted to any other conference or journal. Regular paper submissions are restricted to 15 pages inSpringer's LNCS format, and tool paper submissions are restricted to 4 pages in the same format. Proofs and details omitted due to space constraints may be put in an appendix. Any such additional material will be read by reviewers/program committee members at their discretion. Authors are therefore urged to include details necessary for evaluation of the technical merit of their work within the prescribed page limits. Tool papers must include information about a URL from where the tool can be downloaded or accessed on-line for evaluation. The URL must also contain a set of examples, and a user's manual that describes usage of the tool through examples.

LAST CALL FOR PAPERS Twenty-Eighth Annual ACM/IEEE Symposium on LOGIC IN COMPUTER SCIENCE (LICS 2013) June 25-28, 2013, New Orleans, USA http://lii.rwth-aachen.de/lics/lics13/ LICS 2013 will be hosted by Tulane University, in New Orleans, LA USA, from June 25th to 28th, 2013. LICS 2013 will be co-located with MFPS13 (23-25 June) and CSF13 (28-30 June). The LICS Symposium is an annual international forum on theoretical and practical topics in computer science that relate to logic, broadly construed. We invite submissions on topics that fit under that rubric. Suggested, but not exclusive, topics of interest include: automata theory, automated deduction, categorical models and logics, concurrency and distributed computation, constraint programming, constructive mathematics, database theory, decision procedures, description logics, domain theory, finite model theory, theory of automatic structures, formal aspects of program analysis, formal methods, foundations of computability, higher-order logic, lambda and combinatory calculi, linear logic, logic in artificial intelligence, logic programming, logical aspects of bioinformatics, logical aspects of computational complexity, logical aspects of quantum computation, logical frameworks, logics of programs, modal and temporal logics, model checking, probabilistic systems, process calculi, programming language semantics, proof theory, real-time systems, reasoning about security, rewriting, type systems and type theory, and verification. Important Dates: Authors are required to submit a paper title and a short abstract of about 100 words in advance of submitting the extended abstract of the paper. Titles & Short Abstracts Due : January 7, 2013 Extended Abstracts Due : January 14, 2013 Author Notification (approximate) : March 22, 2013 Final Versions Due for Proceedings: April 26, 2013 Deadlines are firm; late submissions will not be considered. All submissions will be electronic via http://easychair.org/conferences/?conf=lics2013.

The talks will be of similar research interests. http://takeichi.ipl-lab.org/~tops/upcoming_seminar.html Talk 1: Proving open induction using delimited control operators Open Induction (OI) is a principle classically equivalent to Dependent Choice, which is, unlike the later, closed under double-negation translation and A-translation. In the context of Constructive Reverse Mathematics, Wim Veldman has shown that, in presence of Markov's Principle, OI on Cantor space is equivalent to Double-negation Shift (DNS). With Danko Ilik, we have reworked Veldman's proof to give a constructive proof of OI, where DNS is interpreted using delimited control operators. Joint work with Danko Ilik. Talk 2: Walking through infinite trees with mixed induction and coinduction: A Proof Pearl with the Fan Theorem and Bar Induction. We study temporal properties over infinite binary red-blue trees in the setting of constructive type theory. We consider several familiar path-based properties, typical to linear-time and branching-time temporal logics like LTL and CTL*, and the corresponding tree-based properties, in the spirit of the modal mu-calculus. We conduct a systematic study of the relationships of the path-based and tree-based versions of ``eventually always blueness '' and mixed inductive-coinductive ``almost always blueness'' and arrive at a diagram relating these properties to each other in terms of implications that hold either unconditionally or under specific assumptions (Weak Continuity for Numbers, the Fan Theorem, Lesser Principle of Omniscience, Bar Induction). Joint work with Marc Bezem and Tarmo Uustalu.

みなさま，こんにちは！東京大学の蓮尾と申します．先日お知らせした，タリン工科大学の中田景子さんによるご講演ですが，＊＊時間と場所を変更＊＊させてください．（日程は同じです）急なお知らせで申し訳ありません．また，会場の国立情報学研究所では，中田さんのご講演の前（13:30-15:30）に ToPS セミナーが開催されます．そちらにも是非どうぞ！ http://takeichi.ipl-lab.org/~tops/upcoming_seminar.html 蓮尾一郎 http://www-mmm.is.s.u-tokyo.ac.jp/ ============================================= Tue 18 December 2012, 16:00-17:30 Keiko Nakata (Tallinn University of Technology), 2 Talks 国立情報学研究所 12階 1208号室 Rm. 1208, 12F, National Institute of Informatics Access: http://www.nii.ac.jp/en/about/access *** 場所・時間が変わりました *** *** The time and venue have been changed *** 中田さんのご講演の前（13:30-15:30）に，同じ場所で ToPS セミナーが開催されます．そちらにも是非どうぞ！http://takeichi.ipl-lab.org/~tops/upcoming_seminar.h… Prior to Dr. Nakata’s talk there will be a “ToPS seminar” at the same location. The talks will be of similar research interests. http://takeichi.ipl-lab.org/~tops/upcoming_seminar.html Talk 1: Proving open induction using delimited control operators Open Induction (OI) is a principle classically equivalent to Dependent Choice, which is, unlike the later, closed under double-negation translation and A-translation. In the context of Constructive Reverse Mathematics, Wim Veldman has shown that, in presence of Markov's Principle, OI on Cantor space is equivalent to Double-negation Shift (DNS). With Danko Ilik, we have reworked Veldman's proof to give a constructive proof of OI, where DNS is interpreted using delimited control operators. Joint work with Danko Ilik. Talk 2: Walking through infinite trees with mixed induction and coinduction: A Proof Pearl with the Fan Theorem and Bar Induction. We study temporal properties over infinite binary red-blue trees in the setting of constructive type theory. We consider several familiar path-based properties, typical to linear-time and branching-time temporal logics like LTL and CTL*, and the corresponding tree-based properties, in the spirit of the modal mu-calculus. We conduct a systematic study of the relationships of the path-based and tree-based versions of ``eventually always blueness '' and mixed inductive-coinductive ``almost always blueness'' and arrive at a diagram relating these properties to each other in terms of implications that hold either unconditionally or under specific assumptions (Weak Continuity for Numbers, the Fan Theorem, Lesser Principle of Omniscience, Bar Induction). Joint work with Marc Bezem and Tarmo Uustalu.

55th Tokyo Programming Seminar (Dec 18)
by Kazuyuki ASADA 05 Dec '12

05 Dec '12

[Apologies for multiple copies] Dear all, I am pleased to announce the 55th Tokyo Programming Seminar, which will be held at NII on December 18th (Tue). Oleg Kiselyov Non-deterministic choice in a conventional programming language: Enough for logic programming? Hugo Pacheco Bidirectional Data Transformation by Calculation A detailed program is attached below. I'm looking forward to meeting you at the seminar. Best regards, Kazuyuki Asada ---- The 55th ToPS http://takeichi.ipl-lab.org/~tops/upcoming_seminar.html Time: December 18th (Tue) 2012, 13:30--15:30 Place: Rm. 1208, 12F, National Institute of Informatics Speaker: 1. Oleg Kiselyov Non-deterministic choice in a conventional programming language: Enough for logic programming? Abstract: Logic programming is a fascinating approach, especially for AI and natural language processing. It is greatly appealing to declaratively state the properties of the problem and let the system find the solution. Most intriguing is the ability to run programs `forwards' and `backwards'. However, the built-in search methods of logic programming systems don't fit all problems and hardly if at all customizable. Mainly, quite many computations and models are mostly deterministic. Implementing them in a logic programming language is significantly inefficient and requires extensive use of problematic features such as cut. Another problem is interfacing logic programs with mainstream language libraries: if mode analysis is not available (as is often the case), one has to live with run-time instantiatedness errors. An alternative to logic programming, where non-determinism is default, is a deterministic programming system (such as Scheme, OCaml, Scala or Haskell -- or even C) with (probabilistic) non-determinism as an option. Is this a good alternative? We explore this question. We will use Hansei -- a probabilistic programming system implemented as a library in OCaml -- to solve a number of classic logic programming problems, from zebra to scheduling, to parser combinators, to reversible type checking. http://okmij.org/ftp/kakuritu/logic-programming.html 2. Hugo Pacheco Bidirectional Data Transformation by Calculation Abstract: The advent of bidirectional programming, in recent years, has led to the development of a vast number of approaches from various computer science disciplines. These are often based on domain-specific languages in which a program can be read both as a forward and a backward transformation that satisfy some desirable consistency properties. Despite the high demand and recognized potential of intrinsically bidirectional languages, they have still not matured to the point of mainstream adoption. We contemplate some usually disregarded features of bidirectional transformation languages that are vital for deployment at a larger scale. The first concerns efficiency. Most of these languages provide a rich set of primitive combinators that can be composed to build more sophisticated transformations. Although convenient, such compositional languages are plagued by inefficiency and their optimization is mandatory for a serious application. The second relates to configurability. As update translation is inherently ambiguous, users shall be allowed to control the choice of a suitable strategy. The third regards genericity. Writing a bidirectional transformation typically implies describing the concrete steps that convert values in a source schema to values a target schema, making it impractical to express very complex transformations, and practical tools shall support concise and generic coding patterns.

京都大学数理解析研究所の勝股です。 11月29日11:00から、当研究所の照井一成氏が以下の講演をいたしますので、ご連絡いたします。どうぞお気軽にお越しください。 ========== Time: 11:00-12:00, 29 Nov, 2012 Place: Rm 478, Research Building 2, Main Campus, Kyoto University http://www.kyoto-u.ac.jp/en/access/campus/main.htm (See 34) 京都大学本部構内総合研究2号館 4階478号室 http://www.kyoto-u.ac.jp/ja/access/campus/map6r_y.htm (34番の建物) Speaker: Kazushige Terui (RIMS, Kyoto University) Title: Herbrand's theorem via hypercanonical extensions Abstract: よく知られているエルブランの定理を代数的に捉えたい。そのために古典論理のみならず、部分構造論理一般について考える。（様相などの単調／反単調な演算子を追加してもよい。たとえば直観主義論理、単調様相論理、線形論理、ファジー論理など）。 Lをそのような命題論理とし、その最小述語拡大をQLとすると、QLについてエルブランの定理が成り立つための代数的十分条件として、Lに対応する代数のクラスがコンパクトな完備化について閉じていることが挙げられる。そのような完備化の代表例はストーン双対性に基づくものであり、その一般化は正準拡大（canonical extensions）と呼ばれ広く研究されている。しかし部分構造論理の観点から興味深い代数のクラスの多くは、正準拡大について閉じているかどうか定かではない。そこで本講演では、新たなコンパクト完備化として超正準拡大（hypercanonical extensions）を導入する。これは非古典論理証明論における「シークエント計算⇒超シークエント計算」という発想に基づいて正準拡大を一般化したものである。それによりゲーデル＝ダメット論理、monoidal t-norm logicをはじめとする多くの論理についてエルブランの定理が系統的に成り立つことを示す。（今年度MLGにおける講演と同内容）

The appointments are for two years starting in April 2013 (or as soon as possible). A monthly salary of approximately 350,000 Japanese yen plus a research allowance will be offered. Applicants should hold a PhD in theoretical computer science or related fields (or be expected to do so by July 2013). Two of the fellows will be based at the Tokyo site (Tokyo Institute of Technology and the CELC) and two at the Kyoto site (Kyoto University). Collaboration with other research groups of the ELC project (including visits for several months) will be encouraged and supported. Applications should include * a curriculum vitae, * list of publications, * a research statement, and * three letters of referees (to be sent directly from the referees). Applications and letters of referees should be sent via email to elc-pd-application(a)is.titech.ac.jp. Priority will be given to applications received by December 20, 2012. Applicants may be invited to an interview in early 2013 (the travel expenses will be covered). --------- About ELC --------- Exploring the Limits of Computation (ELC) is a five-year research project funded by the Japanese Ministry of Education, Culture, Sports, Science and Technology. Project Title (formal): A multifaceted approach toward understanding the limitations of computation Short Title: Exploring the Limits of Computation (ELC) Project Term: 2012.7 - 2017.3 Researchers have proposed various techniques for investigating the limits of computation, many of which have been sharpened in depth during the last two decades. We may soon be entering the stage of expecting some big breakthrough results toward understanding the limits of computation. In this project, we investigate these techniques and relationships among them with the goal of finding the next steps toward a big breakthrough. We propose the following three lines of research, each of which will be conducted by three core research groups (i.e., nine core research groups altogether). A. Team for pushing the current frontier of research on the limits of computation. B. Team for investigating the limits of computation by using various algorithmic/optimization techniques (even by using supercomputers). C. Team for introducing new approaches to and interpretations of the existing techniques for investigating the limits of computation. We also create a research center (CELC) in Tokyo for investigating computational complexity theory by stimulating worldwide collaborations among researchers based on our core research groups, hosting short/long term visitors and postdoctoral researchers, and organizing various meetings and workshops. We welcome researchers working on subjects related to computational complexity theory to join us for various occasions. Project webpage http://www.al.ics.saitama-u.ac.jp/elc/en/
