Title:
A SECOND LOOK AT PROOF-NETS
Date:
11.00 -, January 12th (Thu)
Place:
Room 478, "Research Bldg. No. 2 (Sougou Kenkyu 2-Goukan)"

Abstract:
In logic, we have a reasonable answer to the question :
"What is a typable object?"
but none so far to the question :
"What is a typed object?"
By a second look at proof-nets, especially the ones involving quantifiers,
we shall propose an answer to the second question.

Title: Static Analysis of Multi-Staged Programs via Unstaging Translation
Abstract:
Static analysis of multi-staged programs is challenging because the
basic assumption of conventional static analysis no longer holds: the
program text itself is no longer a fixed static entity, but rather a
dynamically constructed value. This article presents a
semantic-preserving translation of multi-staged call-by-value programs
into unstaged programs and a static analysis framework based on this
translation. The translation is semantic-preserving in that every
small-step reduction of a multi-staged program is simulated by the
evaluation of its unstaged version. Thanks to this translation we can
analyze multi-staged programs with existing static analysis techniques
that have been developed for conventional unstaged programs: we first
apply the unstaging translation, then we apply conventional static
analysis to the unstaged version, and finally we cast the analysis
results back in terms of the original staged program. Our translation
handles staging constructs that have been evolved to be useful in
practice (typified in Lisp's quasi-quotation): open code as values,
unrestricted operations on references and intentional
variable-capturing substitutions. This article omits references for
which we refer the reader to our companion technical report. This is
a joint work with Wontae Choi, Baris Aktemur, and Makoto Tatsuta.

日時:2012年1月11日(水) 午後2時15分~4時(途中15分休憩)
場所:名古屋大学大学院情報科学研究科棟 322号室

講演者:Franklin D. Tall (トロント大学)
題目:A useful model of set theory
アブストラクト:
I will sketch a method for getting mutually consistent consequences of PFA and V = L.
The talks are unavoidably technical, and assume acquaintance with the method of proper forcing
with elementary submodels as side conditions. The hope is that although listeners are unlikely to
be able to follow all the details presented, they will get enough of the ideas so that they can more
easily study the research papers if they are interested.
多数のご参加をお待ちしております。

Fourth Workshop on
MATHEMATICALLY STRUCTURED FUNCTIONAL PROGRAMMING
25 March, Tallinn, Estonia
A satellite workshop of ETAPS 2012
http://cs.ioc.ee/msfp/msfp2012/
The fourth workshop on Mathematically Structured Functional
Programming is devoted to the derivation of functionality from
structure. It is a celebration of the direct impact of Theoretical
Computer Science on programs as we write them today. Modern
programming languages, and in particular functional languages, support
the direct expression of mathematical structures, equipping
programmers with tools of remarkable power and abstraction. Where
would Haskell be without monads? Functional reactive programming
without arrows? Call-by-push-value without adjunctions? Type theory
without universes? The list goes on. This workshop is a forum for
researchers who seek to reflect mathematical phenomena in data and
control.
The first MSFP workshop was held in Kuressaare, Estonia, in July 2006,
affiliated with MPC 2006 and AMAST 2006. The second MSFP workshop was
held in Reykjavik, Iceland as part of ICALP 2008. The third MSFP
workshop was held in Baltimore, USA, as part of ICFP 2010.
Important Dates:
================
Submission of papers: 23 December 2011
Notification: 25 January 2012
Final versions due: 6 Feburary 2012
Workshop: 25 March 2012
Invited Speakers:
=================
Danko Ilik, Goce Delčev University of Štip, Republic of Macedonia
Neil Ghani, University of Strathclyde, UK
Submission:
===========
Papers must report previously unpublished work and not be submitted
concurrently to another conference with refereed proceedings. Accepted
papers must be presented at the workshop by one of the authors.
There is no specific page limit, but authors should strive for brevity.
Accepted regular papers will be published in the Electronic
Proceedings in Theoretical Computer Science (EPTCS). After the
workshop, there might be an opportunity to publish selected papers in
a journal special issue.
All submissions must be in PDF format and use the EPTCS style
files. Submissions can be made through the EasyChair website, at
http://www.easychair.org/conferences/?conf=msfp2012
ETAPS:
======
European Joint Conferences on Theory and Practice of Software (ETAPS)
is the primary European forum for academic and industrial researchers
working on topics relating to software science. ETAPS, established in
1998, is a confederation of six main annual conferences (one of them,
POST, being new in 2012), accompanied by satellite workshops. ETAPS
2012 is the fifteenth event in the series.
http://www.etaps.org/2012
Host City:
==========
Tallinn, a city of 412,000 people, is the capital and largest city of
Estonia, a small EU member country in Northern Europe, bordering
Russia to the East and Latvia to the south. Located in the north of
the country, on the southern shores of the Gulf of Finland, opposite
Helsinki in Finland, Tallinn is most well known for its picturesque
medieval Old Town, a UNESCO World Heritage site. But it also has a
vivid cultural scene, outperforming most European centres of similar
size. In 2011, Tallinn, along with Turku in Finland, is the Cultural
Capital of Europe.
Tallinn is easy to travel to. Estonia is part of Schengen and the
Eurozone. The Lennart Meri International Airport of Tallinn /TLL) is
only 4km from the city centre.

Logic, Algebra and Truth Degrees 2012
http://www.jaist.ac.jp/rcis/latd12/
First Call for Papers
The third official meeting of the EUSFLAT Working Group on Mathematical
Fuzzy Logic [1] will be held on 10-14 September 2012 in Kanazawa, Japan.
The conference is organized by Research Center for Integrated Science [2],
Japan Advanced Institute of Science and Technology [3].
Mathematical Fuzzy Logic is a subdiscipline of Mathematical Logic which
studies the notion of comparative truth. The assumption that 'truth comes
in degrees' has proved to be very useful in many, both theoretical and
applied, areas of Mathematics, Computer Science and Philosophy.
The main goal of this meeting is to foster collaboration between
researchers in the area of Mathematical Fuzzy Logic, and to promote
communication and cooperation with members of neighbouring fields.
The featured topics include, but are not limited to, the following:
. Proof systems for fuzzy logics: Hilbert, Gentzen, natural deduction,
tableaux, resolution, computational complexity, etc.
. Algebraic semantics: residuated lattices, MTL-algebras, BL-algebras,
MV-algebras, Abstract Algebraic Logic, functional representation, etc.
. Game-theory: Giles games, Rényi-Ulam games, evaluation games, etc.
. First-order fuzzy logics: axiomatizations, arithmetical hierarchy,
model theory, etc.
. Higher-order fuzzy logical systems: type theories, Fuzzy Class Theory,
and formal fuzzy mathematics.
. Philosophical issues: connections with vagueness and uncertainty.
. Applied fuzzy logical calculi: foundations of logical programming,
logic-based reasoning about similarity, description logics, etc.
We also welcome contributions on any relevant aspects of related logical
systems (such as substructural and quantum logics, and many-valued logics
in general).

Speaker: Professor Dr. Peter Vojtas
(Department of Software Engineering of the Charles University in Prague)
Title of the talk: Soundness and completeness of fuzzy Prolog/Datalog.
-------------------------------------------------------------------------
Abstract:
We start with using user preference search as a motivation for
a many valued (fuzzy) model of Prolog/Datalog/Querying. We mention
problems of classical approach with refutation and clausal rules. We
base our semantics on implicative rules and many valued modus ponens. We
prove soundness and completeness of our semantics. We discuss also
clausal approach and fuzzy resolution.

題目: Morley's theorem and Geometric Model Theory
アブストラクト:A countable theory is uncountably categorical if it only has a
unique model (up to isomorphism) on each
uncountable cardinal. Morley proved that a theory is uncountably
categorical if it is categorical on cardinality the continuum.
His proof uses the fact that every model can be built from basic
bricks, called strongly minimal sets (which generalise the
concept of an absolutely irreducible algebraic curve). The goal of
this talk is to give an overview (to a general audience) of
some of the ideas of the proof based on examples. Moreover, we will
link the classification of strongly minimal sets to results
in other areas of mathematics, specially number theory, such as the
existence of infinite Mersenne primes and Schanuel's
conjecture.

Call for papers
*** Non-classical Modal and Predicate Logics ***
special issue of Logic Journal of IGPL
Modalities and predicates have since ancient time been central
notions in logic. In the 20th century, various systems of
non-classical logics have emerged, with applications in many
disciplines like Computer Science, Linguistics, Mathematics,
and Philosophy. This gave rise to the questions of non-classical
treatment of quantification and modalities and their accommodation
in these non-classical settings. In response, various modal and
predicate variants of non-classical logics have been introduced
and studied in the past decades.
This special issue is solely dedicated to modal and predicate
non-classical logics. Its aim is to bring together papers from
various branches of non-classical logics, not only to present
recent advances in the particular fields, but also to identify
common problems and methods and foster the exchange of ideas
between researchers from separate fields.
Topics of interest:
* The study of first- or higher-order variants of non-classical
logics, including, but not limited to:
- Predicate intuitionistic and superintuitionistic logics
- Predicate modal logics
- Predicate substructural logics
- Predicate many-valued and partial logics
- Predicate paraconsistent logics
- Predicate non-monotonic logics, etc.
* Non-classical theories of quantification over classical logic,
such as:
- Free logics
- Branching quantifiers and IF-logic
- Generalized quantifiers
* Extensions by modalities of (propositional or predicate)
non-classical logics, including:
- Modal extensions of (super)intuitionistic, substructural,
many-valued, paraconsistent, non-monotonic, etc., logics
- Co-algebraic treatment of modalities
We encourage to submit papers on the above logics from any
branches of mathematical logic (proof-theory, model theory,
game theory, complexity, etc.), be it purely theoretical or
about applications in the foundation of mathematics, computer
science, linguistics, and philosophy.
== Deadline ==
31 March 2012
== Submissions ==
Papers should be submitted to ncmpl(a)cs.cas.cz. Please also
use this email to express interest in submitting a paper.
== A related conference ==
This special issue is related with the conference Non-classical
Modal and Predicate Logics, organized Guangzhou (Canton), China,

Takayuki Koai (National Institute of Informatics)
Title: Verification of Substitution Theorem Using HOL
Abstract: Substitution Theorem is a new theorem in untyped lambda
calculus, which was proved in 2006. This theorem states that for a
given lambda term and given free variables in it, the term becomes
weakly normalizing when we substitute arbitrary weakly normalizing
terms for these free variables, if the term becomes weakly normalizing
when we substitute a single arbitrary weakly normalizing term for
these free variables. This paper formalizes and verifies this theorem
by using higher-order theorem prover HOL. A control path, which is
the key notion in the proof, explicitly uses names of bound variables
in lambda terms, and it is defined only for lambda terms without bound
variables renaming. The lambda terms without bound variable renaming
are formalized by using the HOL package based on contextual
alpha-equivalence. The verification uses 10119 lines of HOL code and
326 lemmas. This is a joint work with Makoto Tatsuta.
----------------------------------------------------------------------
Mauricio Hernandes (The Graduate University for Advanced Studies)
Title: Game theory from a logician perspective
Abstract: I intend in this talk to introduce a few concepts in game
theory like Nash Equilibrium and Backward-Induction, and then express
those ideas with some modal logic.
----------------------------------------------------------------------
Takanori Hida (Kyoto University)
Title: A computational interpretation of the axiom of determinacy
Abstract: Axiom of determinacy(AD) is a central topic in descriptive
set theory and there are a number of research on this axiom. In this
talk, we approach to the computational content of negative translation
of AD using realizability interpretation due to Berardi, Bezem and
Coquand (1998).
----------------------------------------------------------------------
Makoto Tatsuta (National Institute of Informatics)
Title: Non-Commutative Infinitary Peano Arithmetic
Abstract: Does there exist any sequent calculus such that it is a
subclassical logic and it becomes classical logic when the exchange
rules are added? The first contribution of this paper is answering
this question for infinitary Peano arithmetic. This paper defines
infinitary Peano arithmetic with non-commutative sequents, called
non-commutative infinitary Peano arithmetic, so that the system
becomes equivalent to Peano arithmetic with the omega-rule if the the
exchange rule is added to this system. This system is unique among
other non-commutative systems, since all the logical connectives have
standard meaning and specifically the commutativity for conjunction
and disjunction is derivable. This paper shows that the provability
in non-commutative infinitary Peano arithmetic is equivalent to
Heyting arithmetic with the recursive omega rule and the law of
excluded middle for Sigma-0-1 formulas. Thus, non-commutative
infinitary Peano arithmetic is shown to be a subclassical logic. The
cut elimination theorem in this system is also proved. The second
contribution of this paper is introducing infinitary Peano arithmetic
having antecedent-grouping and no right exchange rules. The first
contribution of this paper is achieved through this system. This
system is obtained from the positive fragment of infinitary Peano
arithmetic without the exchange rules by extending it from a positive
fragment to a full system, preserving its 1-backtracking game
semantics. This paper shows that this system is equivalent to both
non-commutative infinitary Peano arithmetic, and Heyting arithmetic
with the recursive omega rule and the Sigma-0-1 excluded middle. This
is a joint work with Stefano Berardi and was presented at CSL 2011.
----------------------------------------------------------------------
Neil D. Jones (University of Copenhagen)
Title: Termination Analysis of the Untyped lambda-Calculus
Abstract: An algorithm is developed that, given an untyped
lambda-expression, can certify that its call-by-value evaluation will
terminate. It works by an extension of the ``size-change principle''
earlier applied to first-order programs. The algorithm is sound (and
proven so) but not complete: some lambda-expressions may in fact
terminate under call-by- value evaluation, but not be recognised as
terminating. The intensional power of size-change termination is
reasonably high: It certifies as terminating all primitive recursive
programs, and many interesting and useful general recursive algorithms
including programs with mutual recursion and parameter exchanges, and
Colson's ``minimum'' algorithm. Further, the approach allows free use
of the Y combinator, and so can identify as terminating a substantial
subset of PCF. (joint work with Nina Bohr; in Logical Methods in
Computer Science, 2008, Issue 1)
----------------------------------------------------------------------
Stefano Berardi (Torino University)
Title: A Topology over a set of Knowledge States and a Fixed Point Problem
Abstract: We give an abstract formulation of the termination problem
for realizer of Heyting Arithmetic plus various subsystem of classical
logic. This termination problem is expressed as the existence of a
fixed point for a class of continuous maps in a suitable topology.

タイトル:
Dilators: a gentle introduction
講演の概要:
We aim to recall some basic aspects of the concept of dilator, a
notion which has been introduced in proof-theory (a branch of
mathematical logic) by J.-Y. Girard about 30 years ago.
Essentially, a dilator is a certain kind of endofunctor of the category
of the ordinal numbers, which can be thought as an abstract counterpart
of the more concrete system of ordinal notation which are abundant in
proof-theory.
In this introductory talk, we recall the notion of denotation system (a
kind of generalization of the Cantor normal form representation of the
ordinal numbers), the notion of dilator, and show a correspondence
between them.
