(重複して受け取られた場合はご容赦ください) 京都大学数理解析研究所の佐藤です。 10月29日11:00から、チェコ科学アカデミーのPetr Cintula氏に以下の講演をしていただくことになりましたので、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 Oct, 2015 Place: Rm 478, Research Building 2, Main Campus, Kyoto University 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/en/access/yoshida/main.html (Building 34) http://www.kyoto-u.ac.jp/ja/access/campus/map6r_y.htm (34番の建物) Speaker: Petr Cintula (The Czech Academy of Sciences) Title: Logic and mathematics with lattice-valued predicates Abstract: Classical predicate logic interprets n-ary predicates as mappings from the n-th power of a given domain into the two-valued boolean algebra 2. The idea of replacing 2 by a more general structure is very natural and was shown to lead to a very interesting mathematics: prime examples are the boolean-valued or Heyting-valued models of set theory (or even more general models proposed by Takeuti & Titani (1992), Titani (1999), and Hajek & Hanikova (2001)). In the first part of the talk we present a framework for the study of logics where predicates can take values in a lattice (with additional operators) from a given class satisfying certain minimal conditions (our framework covers previous approaches of Rasiowa & Sikorski (1963), Horn (1969), Rasiowa (1974), Hajek (1998), and others). For each such logic we first describe its `propositional' part and then use it to give an axiomatization of the full first-order logic. The second part of the talk shows that the proposed logical formalism is rich enough to support non-trivial mathematical theories. We illustrate it by proving `graded' variant of the well-know relation between equivalences and partitions. The goal of the example is to illustrate the contrast between very general semantical interpretation of the proven fact and its almost classical proof.

Building on two communities, RTA (Rewriting Techniques and Applications) and TLCA (Typed Lambda Calculi and Applications), FSCD embraces their core topics and broadens their scope to closely related areas in logics, proof theory and new emerging models of computation such as quantum computing and homotopy type theory. The name of the new conference comes from an unpublished but important book by Gerard Huet that strongly influenced many researchers in the area. Suggested, but not exclusive, list of topics for submission are: 1 Calculi * Lambda calculus * Logics (first-order, higher-order, equational, modal, linear, classical, constructive, etc.) * Rewriting systems (string, term, higher-order, graph, conditional, modulo, infinitary, etc.) * Proof theory (natural deduction, sequent calculus, proof nets, etc.) * Type theory and logical frameworks * Homotopy type theory 2. Methods in Computation and Deduction * Type systems (polymorphism, dependent, recursive, intersection, session, etc.) * Induction, coinduction * Matching, unification, completion, orderings * Strategies (normalization, completeness, etc.) * Tree automata * Model building and model checking * Proof search (resolution, paramodulation, narrowing, focusing, etc.) * Constraint solving and decision procedures 3. Semantics * Operational semantics and abstract machines * Game Semantics and applications * Domain theory and categorical models * Quantitative models (timing, probabilities, resources, etc.) * Quantum computation and emerging models in computation 4. Algorithmic Analysis and Transformations of Formal Systems * Type Inference and type checking * Abstract Interpretation * Complexity analysis and implicit computational complexity * Checking termination, confluence, derivational complexity and related properties * Symbolic computation 5. Tools and Applications * Programming and proof environments (proof assistants, automated theorem prover, proof checkers, specialized provers, dependently typed languages, etc.) * Verification tools (abstract interpretation, termination, confluence, specialized provers, etc.) * Libraries for proof assistants and interactive theorem provers (support for variable bindings, nominal, polynomial, equality, etc.) * Case studies in proof assistants and interactive theorem provers (formalizations, mechanizations, certifications) * Certifications (theorems, rewriting techniques, etc.) * Applications of formal systems inside and outside of CS (biology, linguistics, physics, education, etc.) INVITED SPEAKERS Amal Ahmed (USA) Ichiro Hasuo (Japan) Gerard Huet (France) Tobias Nipkow (Germany) PROGRAM CHAIRS Delia Kesner (Univ.

In particular, we are hoping that more attention in future research will be paid to the study of philosophical logic, specifically, the study of the construction, and application, of logical framework appropriate for not only the analysis of philosophical concepts, but also the theorization of philosophical doctrines. For further information, see http://www.philo.ntu.edu.tw/lmmgroup/ <https://mail.ntu.edu.tw/owa/redir.aspx?SURL=VQSmOL0kp3hcT3CTqb3Xk6CFzdirbbX…> In view of the substantial contribution that Professor Timothy Williamson has made in the last few decades to contemporary philosophy, the organizing committee has set as the ultimate priority to organize a one-day plus workshop on Williamson’s philosophy during the joint conference. This project has been approved by Professor Williamson and more importantly he has accepted our invitation to come and join us on this special occasion. The Core Special attention will be paid to Williamson’s five seminal books: Identity and Discrimination, 2nd ed. (1st ed. 1990), Oxford: Blackwell, 2013. Vagueness, London: Routledge, 1994. Knowledge and Its Limits <http://en.wikipedia.org/wiki/Knowledge_and_Its_Limits>, Oxford: Oxford University Press, 2000. The Philosophy of Philosophy, Oxford: Blackwell, 2007. Modal Logic as Metaphysics, Oxford: Oxford University Press, 2013. The format (The workshop will contain at least 7 sessions) The workshop will start with a keynote speech by Williamson, followed by four sessions on the 6th of October, and will be continued, together with a final session for Williamson’s replies on the 7th of October. 1st session (90 mins): A brief introduction (about 5-10 minutes) of Williamson’s contribution in the last few decades (by the chair) A keynote speech (about 60 minutes plus 10-20 minutes for discussion) by Timothy Williamson 2nd-6th sessions: Each session (90 minutes) focuses on one of Williamson’s five books, and includes 4 parts: (3-5 minutes) An introduction to the book under discussion (by the chair) (60-70 minutes) One talk by an invited speaker, followed by a contributed talk. (10-15 minutes) Williamson’s replies. (10-15 minutes) Discussion 7th session (90 minutes): (5-10 minutes) A summary from the chair (30-40 minutes) a final response from Williamson (especially to the talks which are not included in the special workshop) (20-30 minutes) discussions. Submission of Abstracts for Contributed Talks All researchers who are interested in Williamson’s philosophy are cordially invited to submit their abstracts by 30 April 2016. Authors should submit an (extended) abstract no less than one page but no more than four pages (A4 size, single space). Abstracts must be submitted as PDF files and sent to D.-M. Deng [dmdeng(a)ntu.edu.tw <mailto:dmdeng@ntu.edu.tw>] S.C.-M. Yang [cmyang(a)ntu.edu.tw] Memo: 1. Associated with each book, there is at least one session, containing two talks to address some issues on the themes of that book. 2. The organizing committee have also invited some renowned scholars to focus on the themes of each book, if possible. So far we have invited: Katalin Farkas (Central European University, Hungary, on themes from Identity and Discrimination.) Greg Restall (University of Melbourne, Australia, on themes from Modal Logic as Metaphysics.) Nick Smith (University of Sydney, Australia, on themes from Vagueness) 3. Extra contributed talks will be welcome. If the accepted abstracts for contributed talks on Williamson’s philosophy are more than originally scheduled, the Programme Committee will be very glad to put the extra ones in some other sessions before the conclusion session so that Williamson may have some comments/replies to those speakers as well. 4. A full length manuscript of a contributed talk on this workshop should be sent to the organizer by the 15th of September 2016 in order for Professor Williamson to read it before the workshop. 5. The chair of each session will provide a brief survey of the book (that session focuses on). 6. The organizing committee will try to find some well-known publisher to consider the possibility of publishing a post-conference proceedings, provided this proposal is approved by Williamson. The details will be announced when this proposal is also approved by the publisher. 7. A final remark: Professor Williamson has thoughtfully promised to offer young scholars in Taiwan, who contribute papers to this workshop, a one-on-one tutorial/supervision to discuss their papers before the conference. Tutorial time will be scheduled in two afternoons before the conference. [The details will be announced in due course.] For any enquiry/information please contact: D.-M. Deng (dmdeng(a)ntu.edu.tw <mailto:dmdeng@ntu.edu.tw>) S. C.-M. Yang (cmyang(a)ntu.edu.tw <mailto:cmyang@ntu.edu.tw>)

Each workshop is open to all philosophers and logicians around these regions, who share a certain common interest in a variety of logical/philosophical issues. The scope of the Workshop includes, but not exclusively, the family of non-classical logics, algebraic logic, computer science, cognitive science, linguistics, game theory, etc., and their applications in a variety of philosophical issues. The First Asian Workshop on Philosophical Logic (AWPL-2012) was held at the Research Center for Integrated Science <http://www.jaist.ac.jp/rcis/> (RCIS), Japan Advanced Institute of Science and Technology <http://www.jaist.ac.jp/> (JAIST) on February 15-17, 2012. More than twenty scholars were invited and a special session for discussing the possibility of collaborations in the near future. It was then widely agreed that the workshop should be extended to a biennial event henceforth. The Second Asian Workshop on Philosophical Logic (AWPL-2014) was held at the Institute of Logic and Cognition, Sun Yat-sen University, April 12-13, 2014. A collection based on some selected papers from AWPL-2014, entitled ‘Modality, Semantic and Interpretation’, was published as the first volume of the book series ‘Logic in Asia’ (LIAA) by Springer. Appendix B INTRODUCTION TO TAIWAN PHILOSOPHICAL LOGIC COLLOQUIUM (TPLC-SERIES) TPLC is a series of biennial conferences established since 2012 and is hosted by Department of Philosophy, National Taiwan University, Taiwan. The aim of the TPLC-series is to provide a forum for dialogues amongst philosophers and logicians with regard to a variety of issues and topics of current interest. We intend to bring together a group of logic-minded philosophers and philosophically oriented logicians so as to promote the development of logic and analytic philosophy in Asian area, especially in Taiwan. The TPLC-series are open not only to interested local scholars. We also invite several distinguished international scholars as plenary/keynote/invited speakers and welcome contributed talks from abroad as well. To strengthen a closer connection with other philosophy communities in the neighbourhood, at the early stage of this series, the invited philosophers and logicians are mainly from Asian and Australasian regions. The scope of this series of colloquium will cover: philosophical logic (in a broad sense), non-classical logics, algebraic logic, all kinds of semantics/logics relating to metaphysical/epistemological concepts and some issues in philosophy of language, philosophy of logic/mathematics, and their applications in computer science and cognitive science. The first Taiwan Philosophical Colloquium (TPLC-2012) was held on December 7, 2012; and TPLC-2014 was held on October 24-25, 2014. Apart from two keynote speeches delivered by Robert Goldblatt and Hiroakira Ono, there were sixteen invited/ contributed talks by scholars from Australia, China, Japan, Hong Kong, Netherlands, and local scholars. A post-conference proceedings of TPLC-2014, entitled Structural Analysis of Non-Classical Logics, will be published as the second volume of the newly established book series ‘Logic in Asia’ (LIAA), by Springer in October 2015.

19 Sep '15

Logic, Algebra and Truth Degrees (LATD) 2016 28 - 30 June 2016 Phalaborwa, South Africa First Announcement The fifth instalment of the conference Logic, Algebra and Truth Degrees (LATD) will take place in Phalaborwa, South Africa from 28 - 30 June 2016. The conference will be hosted by the Faculty of Science of the University of the Witwatersrand, Johannesburg, at the Hans Merensky Hotel, situated on the border of the world renowned Kruger National Park Game Reserve. Detailed travel information is available on the conference website. Mathematical Fuzzy Logic is the sub-discipline of Mathematical Logic that is concerned with the notion of comparative truth. The assumption that "truth comes in degrees" has proved to be very useful in many theoretical and applied areas of Mathematics, Computer Science, and Philosophy. This conference series started as an official meeting of the working group on Mathematical Fuzzy Logic and has evolved into a wider meeting in algebraic logic and related areas. Its main goal is to foster collaboration between researchers in these areas, and to promote communication and cooperation with members of neighbouring fields. We encourage contributions on any relevant aspects of logical systems (including fuzzy, substructural, modal and quantum logics, and many-valued logics in general). The featured topics include: - Proof theory and computational complexity - Algebraic semantics and abstract algebraic logic - First, higher-order and modal formalisms - Applications and foundational issues - Geometric and game theoretic aspects Potential participants are encouraged to complete the expression of interest form: http://www.latd2016.co.za/ExpressionOfInterest.html <http://www.latd2016.co.za/ExpressionOfInterest.html> Important Dates: Deadline for submissions: 24 February 2016 Notification of acceptance: 31 March 2016 Early registration closes: 27 April 2016 Registration closes: 15 June 2016 Conference dates: 28 - 30 June 2016 Programme committee: James Raftery (Chair), University of Pretoria Xavier Caicedo, Universidad de los Andes Agata Ciabattoni, Vienna University of Technology Petr Cintula, Czech Academy of Sciences Nikolaos Galatos, University of Denver Rostislav Horcik, Czech Academy of Sciences Rosalie Iemhoff, Utrecht University, The Netherlands Hiroakira Ono, Japan Advanced Institute of Science and Technology Philip Scott, University of Ottawa.

The methods to be looked into are heavily involved with checking whether or not two models (or two classes of models) stand in certain relations. Here the two most-checked relations between two models are back-and-forth equivalence and definability (that is, defining one into another). In this light, this talk will also briefly discuss some general theorems concerning the two aforementioned model theoretical relations. -- Katsuhiko Sano School of Information Science Japan Advanced Institute of Science and Technology IS building No.1 7F, 1-1 Asahidai, Nomi, Ishikawa, 923-1292, Japan

FLOPS2016 論文募集 (deadline extension)
by Yukiyoshi Kameyama 08 Sep '15

08 Sep '15

皆様、(重複して受け取られた場合は、御容赦ください。) 国際会議FLOPS2016 -- Functional and Logic Programming -- の論文募集(最終)をお送りします。投稿締切が延長され、9/25 (any time zone) となっています。 (abstract の締切は 9/21 (any time zone) です。) 論文投稿をよろしくおねがいします。 -- 亀山幸義 (筑波大学) http://logic.cs.tsukuba.ac.jp/~kam ------------------------------------------------------------------------------ NEW: revised submission deadlines (Sep 21 for abstracts, Sep 25 for papers) FLOPS 2016: March 3-6, 2016, Kochi, Japan Final Call For Papers http://www.info.kochi-tech.ac.jp/FLOPS2016/ Writing down detailed computational steps is not the only way of programming. The alternative, being used increasingly in practice, is to start by writing down the desired properties of the result. The computational steps are then (semi-)automatically derived from these higher-level specifications. Examples of this declarative style include functional and logic programming, program transformation and re-writing, and extracting programs from proofs of their correctness. FLOPS aims to bring together practitioners, researchers and implementors of the declarative programming, to discuss mutually interesting results and common problems: theoretical advances, their implementations in language systems and tools, and applications of these systems in practice. The scope includes all aspects of the design, semantics, theory, applications, implementations, and teaching of declarative programming. FLOPS specifically aims to promote cross-fertilization between theory and practice and among different styles of declarative programming. Scope FLOPS solicits original papers in all areas of the declarative programming: * functional, logic, functional-logic programming, re-writing systems, formal methods and model checking, program transformations and program refinements, developing programs with the help of theorem provers or SAT/SMT solvers; * foundations, language design, implementation issues (compilation techniques, memory management, run-time systems), applications and case studies. FLOPS promotes cross-fertilization among different styles of declarative programming. Therefore, submissions must be written to be understandable by the wide audience of declarative programmers and researchers. Submission of system descriptions and declarative pearls are especially encouraged. Submissions should fall into one of the following categories: * Regular research papers: they should describe new results and will be judged on originality, correctness, and significance. * System descriptions: they should contain a link to a working system and will be judged on originality, usefulness, and design. * Declarative pearls: new and excellent declarative programs or theories with illustrative applications. System descriptions and declarative pearls must be explicitly marked as such in the title. Submissions must be unpublished and not submitted for publication elsewhere. Work that already appeared in unpublished or informally published workshops proceedings may be submitted. See also ACM SIGPLAN Republication Policy.

皆様ジーゲン大学のDieter Spreen先生の講演のお知らせです。どうぞふるってご参加ください。問合せ先：石原　哉北陸先端科学技術大学院大学情報科学研究科 e-mail: ishihara(a)jaist.ac.jp ----------------------------------------------- * JAIST Logic Seminar Series * * This seminar is held as a part of JSPS Core-to-Core Program, A. Advanced Research Networks, and EU FP7 Marie Curie Actions IRSES project COMPUTAL (http://computal.uni-trier.de/). Date: Thursday 7 May, 2015, 13:30-15:00 Place: JAIST, Collaboration room 6 (I-57g) (Access: http://www.jaist.ac.jp/english/location/access.html) Speaker: Dieter Spreen (University of Siegen) Title: Digit Spaces - Topological Foundations Abstract: Digit spaces have been introduced by Ulrich Berger as a framework for extracting programs that deal with continuous data from formal proofs. The essential idea was to represent objects as streams of unary contractions on a complete metric space and to use coinduction on the logical side. In recent joint work on an extension of this approach to hyperspaces like the space of nonempty compact subsets of a digit space, it turned out that compact cannot be represented by such streams in general: instead one has to deal with infinite trees the nodes of which are labeled by contraction similar to the stream case. It was realized, however, that one will obtain a uniform theory, if the contractions, also called digits, are allowed to be multi-ary.

We adopt the infinite-regress logic EIR² (a fixed-point extension) of the epistemic logic KD² to capture individual decision making from the viewpoint of logical inference. In the logic EIR², prediction/decision making is described by the belief set Δ_{i}(g) for player i, where g specifies a game. Our results on prediction/decision making differ between solvable and unsolvable games. For the former, we show that player i can decide whether each of his strategies is a final decision or not. For the latter, we obtain undecidability, i.e., he can neither decide some strategy to be a possible decision nor disprove it. Thus, the theory (EIR²;Δ_{i}(g)) is incomplete in the sense of Gödel's incompleteness theorem for an unsolvable game g. This result is related to "self-referential", but its main source is a discord generated by interdependence of payoffs and independent prediction/decision making. Ryota Akiyoshi (Waseda Institute for Advanced Study): "Some results in proof-theory for $\Pi^{1}_{1}$-$CA$" Abstract: In 2000's, Tait asked the question whether we can prove without ordinal notations that all proofs in $\Pi^{1}_{1}$-$CA$ with (Sch\"{u}tte's) $\omega$-rule are transformed into cut-free ones. Inspired by this, the author and Mints formulated an extension of Buchholz' $\Omega$-rule using Takeuti's distinction of explicit/implicit inference and proved the complete cut-elimination theorem for it. An answer to Tait's question is given by combining this with the author's work on "finite notations for infinitary derivations" for this kind of $\Omega$-rule. In the first part of the talk, we will explain the result with Mints. Next, we explain a connection between the $\Omega$-rule and the computability predicate by Tait-Girard. In 2008, Mints suggested that there should be a connection between these two methods because they would have a common aim to solve the difficulty how to deal with the substitution of a set term $T$ into a free second-order variable $X$ in $A(X)$. The author and Terui recently found this connection by formulating the $\Omega$-rule in the framework of the computability. We report and discuss our result. Wilfried Sieg (Carnegie Mellon University) "Dedekind's structuralism: creating concepts and deriving theorems" Abstract: Dedekind's structuralism is a crucial source for the structuralism of mathematical practice with its focus on abstract concepts like groups and fields. It plays an equally central role for the structuralism of philosophical analysis with its focus on particular mathematical objects like natural and real numbers. Tensions between these structuralisms are palpable in Dedekind's work, but are resolved in his essay Was sind und was sollen die Zahlen? In a radical shift, Dedekind extends his mathematical approach to “the” natural numbers. He creates the abstract concept of a simply infinite system, proves the existence of a “model”, insists on the stepwise derivation of theorems, and defines structure-preserving mappings between different systems that fall under the abstract concept. Crucial parts of these considerations were added only to the penultimate manuscript, for example, the very concept of a simply infinite system. The methodological consequences of this radical shift are elucidated by an analysis of Dedekind's metamathematics. Our analysis provides a deeper understanding of the essay and, in addition, illuminates its impact on the evolution of the axiomatic method and of “semantics” before Tarski. This understanding allows us to make connections to contemporary issues in the philosophy of mathematics and science. (This reports on work with Rebecca Morris.) 9/11: Yuta Takahashi (Keio University) "Gentzen's 1935/36 Consistency Proofs as Means of Ascribing Constructive Senses" Abstract: Gentzen's three consistency proofs for number theory have a common aim that originates from Hilbert's Program, namely, the aim to justify the application of classical reasoning to quantified propositions in number theory. In addition to this common aim, Gentzen gave a constructive interpretation to every number-theoretic proposition in his 1935/36 consistency proofs, while Hilbert's Program included no such interpretation. In this talk, we claim that Gentzen's interpretation took a part of his response to an objection posed by Brouwer against the significance of consistency proofs. Specifically, we argue as follows. According to Brouwer, consistency proofs for classical mathematics are of no significance, because its theorems have no sense whether or not its consistency is proved by using the methods of the Hilbert School. In order to respond to this objection, Gentzen aimed at ascribing a constructive sense to each theorem of classical number theory by means of his interpretation. Mitsuhiro Okada (Keio University) "Husserl's universal arithmatic and his proof theoretical view of formal mathematics" Abstract: We discuss Husserl's development of the conception of universal arithmatic,, with the special focus on his Double-Lecture and other manuscripts in 1901. We can see how his work is influenced from former formalists' work and, at the same time, how it is sharply contrasted to those,. such as Hankel's and Hilbert's former work. We discuss Husserl's view of proof-theoretic and computational notion of "manifold (in his own sense), and his term-rewrite theoretic notion of "definiteness" of manifold. We also discuss some significance of the Husserlian proof theoretic view of mathematics as well as some limitation (for which Wittgenstein partly solved much later). Wilfried Sieg (Carnegie Mellon University) "The ways of Hilbert's axiomatics: structural and formal" Abstract: It is a remarkable fact that Hilbert's programmatic papers from the 1920s still shape, almost exclusively, the standard contemporary perspective of his views concerning (the foundations of) mathematics; even his own, quite different work on the foundations of geometry and arithmetic from the late 1890s is often understood from that vantage point. My essay pursues one main goal, namely, to contrast Hilbert's formal axiomatic method from the early 1920s with his existential axiomatic approach from the 1890s, deeply influenced by Dedekind. Such a contrast illuminates the circuitous beginnings of the finitist consistency program and connects the complex emergence of existential axiomatics with transformations in mathematics and philosophy during the 19th century; the sheer complexity and methodological difficulties of the latter development are partially reflected in the well known, but not well understood correspondence between Frege and Hilbert. Taking seriously the goal of formalizing mathematics in an effective logical framework leads also to contemporary tasks, not just historical and systematic insights.

In logic, a (ideal) mathematician calculates/proves a target theorem from his assumptions. An engine for such adjustments and calculations is logical inference. Such behavior is of a highly symbolic nature. However, it has been customary in the fields of mathematics as well as game theory that real targets are actual models but not symbolic expressions (axiomatizations). This attitude should be reversed when we take game theory as a serious study of human behavior/decision-making in social contexts including considerations of experiential sources for individual beliefs. This is very compatible with the basic idea of “symbolic” logic. In this presentation, we discuss various problems related to this interpretation. [Speaker] Masahiko Sato (Kyoto University) [Title] Proof theory of the lambda-calculus [Abstract] We present a new representation of lambda-terms as a subalgebra of a free algebra. As elements of the free algebra, lambda-terms are constructed without employing the abstraction operation, and this construction of lambda-terms enables us to study lambda-terms as natural finitary objects. In this setting, we will develop the lambda-calculus by defining reductions as derivations and study the proof theory of the lambda-calculus. We will develop the theory in the Minlog proof assistant developed by Helmut Schwichtenberg. [Speaker] Wilfried Sieg (Carnegie Mellon University) [Title] The *concept *of computation - an axiomatic characterization [Abstract] Computations are pervasive in contemporary science and life; they are visible everywhere. However, the *concept *of computation emerged in an almost invisible corner of our intellectual life. I will describe the context for the emergence of computability as a crucial notion in mathematics and logic with a normative philosophical component. My analysis of the emergence of this concept provides a novel perspective on *the central methodological issue *that surrounds computations, the “Church-Turing Thesis”. We focus on *calculable functions *on natural numbers and *mechanical operations *on syntactic configurations. The latter analysis leads to boundedness and locality conditions that motivate axioms for *computable dynamical systems*. Models of these axioms are all reducible to Turing machines. Cellular automata and a variety of artificial neural nets can be shown to satisfy them. Finally, I draw connections and point out directions for fascinating work. As to connections, I will emphasize that my novel perspective is rooted in the radical transformation of mathematics of the 19th century; especially, in the new form of structural axiomatics introduced by Dedekind and Hilbert. [Speaker] Yasuo Deguchi (Kyoto University) [Title] Kant on mathematical intuition: from an educational point of view [Abstract] Kantian notion of mathematical intuition has been criticized, notably by Frege, as too psychological or private to be the proper base of mathematics. This talk will challenge such an allegation by paying attentions to its historical backgrounds, especially that of German mathematical education. First, it focuses on Kantian notion of arithmetical intuition, and identifies one of its main resources; ’Segner’s arithmetic'. Since Vaihinger published his influential commentary of the first critique, Kantians of many variants have almost unanimously believed that it was one of his books; i.e., ‘Principle’. But this talk claims that it is his another book; i.e., ‘Lectures’. Segner’s ‘Lecture’ rather than ‘principle’ occupies a significant position in German history of mathematical education: it is a complement to the pedagogical tradition, so called, 'formal cultivation’ that was initiated by Ch. Wolff. In ‘Lectures', Segner employed such intuitive representations of numbers as points and asterisks, to make the rigid formality of mathematical thinking more approachable to the younger audiences. Since Segner’s intuitive examples of numbers and arithmetic operations were intended to be used in the context of classroom education, they should be publicly available for both teachers and students, and therefore visible and even manipulatable. Based on those observations, this talk claims that Kantian notion of mathematical intuition inherited this visibility, manipulability and public nature of Segner’s exemplars, and is not to be interpreted as being psychological or private. [Speaker] Makoto Kikuchi (Kobe University) [Title] Aspects of the notion of computability [Abstract] There are two important subclasses of the set of partial recursive functions. One is the set of primitive recursive functions and the other is the set of general or total recursive functions. The notion of computability had been scrutinized and expanded in 1930's and nowadays it is widely believed that we have succeeded in formulating the notion of computability accurately and adequately by reaching the concept of partial recursive functions. In this talk, we observe the two gaps of the three classes of computable functions and argue that the former expansion from primitive recursive functions to general recursive functions is somewhat mathematical while the latter enlargement from general recursive functions to partial recursive functions is rather philosophical. We discuss also consequences of observations of the discontinuity in the latter transition in the notion of computability.
