（重複の場合はご容赦ください） 7月にWarwickで開催される古典論理と計算に関するワークショップの論文募集です．締切りが大幅に延長されておりますので，是非，投稿をご検討ください．中澤 International Workshop on Classical Logic and Computation (CL&C'12) http://www.doc.ic.ac.uk/~svb/CLaC12 July, 8 2012 Warwick, England CL&C'12 is a satellite workshop of ICALP'12. IMPORTANT DATES Abstract submission (canceled) Deadline for submission: April, 23, 2012 (new) Notification of acceptance: June, 18, 2012 (new) Final version due: June, 28, 2012 (new) Workshop date: July, 8, 2012 INTRODUCTION CL&C'12 is the fourth of a conference series on Classical Logic and Computation. It intends to cover all work aiming to explore computational aspects of classical logic and mathematics. This year CL&C will be held as satellite workshop of ICALP'12 in Warwick: http://www2.warwick.ac.uk/fac/cross_fac/dimap/icalp2012/ CL&C is focused on the interplay between program extraction from classical the exploration of the computational content of mathematical and logical principles. The scientific aim of this workshop is to bring together researchers from both fields and exchange ideas. SCOPE OF CL&C This workshop aims to support a fruitful exchange of ideas between the various lines of research on Classical Logic and Computation. Topics of interest include, but are not limited to, - version of lambda calculi adapted to represent classical logic; - design of programming languages inspired by classical logic; - cut-elimination for classical systems; - proof representation and proof search for classical logic; - translations of classical to intuitionistic proofs; - constructive interpretation of non-constructive principles; - witness extraction from classical proofs; - constructive semantics for classical logic (e.g. game semantics); - case studies (for any of the previous points). SUBMISSION AND PUBLICATION. This is intended to be an informal workshop. Participants are encouraged to present work in progress, overviews of more extensive work, and programmatic / position papers, as well as completed projects. We therefore ask for submission both of short abstracts and of longer papers. All submitted papers will be reviewed to normal standards. The PC recognises two kinds of papers: it will distinguish between accepted (full) papers that contain unpublished results not submitted elsewhere, and presentations of (short) papers about work in progress. The accepted papers will appear in EPTCS. In order to make a submission: - Format your file using the LNCS guidelines; there is a 15 page limit. - Use the submission instructions at https://www.easychair.org/conferences/?conf=clc2012 A participants' proceedings will be distributed at the workshop. PROGRAMME COMMITTEE * Herman Geuvers (Nijmegen) - chair * Stefano Berardi (Turin) * Steffen van Bakel (Imperial College London) * Silvia Ghilezan (Novi Sad) * Koji Nakazawa (Kyoto Univeristy) * Ugo de'Liguoro (Turin) CONTACT deligu(a)di.unito.it

東北大学の赤間陽二さんの依頼により投稿します。　　小野寛晰 ---------------------------------------------------------------------------------------------- 　　　　　　Seminar Announcement Anyone can come! Speaker: Norbert Preining (JAIST) Title: Goedel Logics, Continuous Embeddability and Fraisse's Conjecture Date: Wednesday, 4 April, 16:00---17:40 Venue: 802, Rigaku Sogo-to (Godo-to), 8F, Science Campus, Tohoku University Key words: many-valued logic, order theory, semantics In this talk we present a family of many-valued logics introduced by Kurt Goedel to approximate Intuitionistic Logic. Later on these were extended to first order and have exhibited connections to temporal logics, Kripke frames based logics, fuzzy logics in the sense of Hajek (t-norm based logics). These logics are based on selecting a closed subset of the real interval [0,1], and collecting all formulas evaluating to true for all valuations into this truth value set. Due to the specific truth functions different truth values sets might generate the same logics (as sets of formulas). During the search for the total number of logics we took up old conjecture of Fraisse (theorem of Laver) on the behaviour of scattered linear orderings. We consider continuous embeddability in the reals and prove a generalized Fraisse conjecture stating the the closed subsets of the real [0,1] interval with continuous embeddability are better-quasi-ordered. Using this result we can show that surprisingly the total number of different Goedel logics is countable. This discrepancy - on the one hand uncountable many equivalence classes of the above mentioned ordering, and countable many Goedel logics on the other hand - leaves us still without an "intensional definition" of Goedel logics in the sense that if two semantical objects (to be found or defined) are different, then the respective logics are different, too. This does not hold for equality of the truth value sets, since there are different truth value sets creating the same logic, as well as for the above mentioned continuous embeddability induced equivalence. ======================================== Short biography of Norbert Preining * Graduated from Vienna University of Technology under the auspicies of the president of the Republic of Austria in 2003 * Postdoc in Siena, Italy as European Community Marie Curie Fellow * Project leader of a research project of the Austrian Research Fund (FWF) (paralleling the JSPS) * Currently Associate Professor at the JAIST * Secretary of the Kurt Goedel Society, responsible for the Kurt Goedel Research Prize Fellowship * Spare time activities are montaineering, typography, TeX, and Debian Contact: Yohji Akama (Mathematical Institute, Tohoku University) akama(a)m.tohoku.ac.jp, 022-795-7708 For the access, See map on http://www.math.tohoku.ac.jp/access/index.html or http://www.math.tohoku.ac.jp/english/access-e.html　（english).

TARK 2013 Call for Papers
by Suzuki, Nobu-Yuki 02 Apr '12

02 Apr '12

*Call for Papers* TARK 2013 14. Conference on Theoretical Aspects of Rationality and Knowledge January 7-9, 2013 Institute of Mathematical Sciences, Chennai, India Conference website: http://www.imsc.res.in/tark/ About the Conference The mission of the TARK conferences is to bring together researchers from a wide variety of fields, including Artificial Intelligence, Cryptography, Distributed Computing, Economics and Game Theory, Linguistics, Philosophy, and Psychology, in order to further our understanding of interdisciplinary issues involving reasoning about rationality and knowledge. Topics of interest include, but are not limited to, semantic models for knowledge, belief, awareness and uncertainty, bounded rationality and resource-bounded reasoning, commonsense epistemic reasoning, epistemic logic, epistemic game theory, knowledge and action, applications of reasoning about knowledge and other mental states, belief revision, and foundations of multi-agent systems. Submissions are now invited to TARK 2013. Extended Abstracts can be submitted here: https://www.easychair.org/conferences/?conf=tark2013 Strong preference will be given to papers whose topic is of interest to an interdisciplinary audience, and papers should be accessible to such an audience. Papers will be held to the usual high standards of research publications. In particular, they should 1) contain enough information to enable the program committee to identify the main contribution of the work; 2) explain the significance of the work -- its novelty and its practical or theoretical implications; and 3) include comparisons with and references to relevant literature. Abstracts should be no longer than ten double-spaced pages (4,000 words). Optional technical details such as proofs may be included in an appendix. An email address of the contact author should be included. Papers arriving late or departing significantly from these guidelines risk immediate rejection. One author of each accepted paper will be expected to present the paper at the conference. Economists should be aware that special arrangements have been made with certain economics journals (in particular, with International Journal of Game Theory, Games and Economic Behavior, Journal of Economic Theory, and Mathematical Social Sciences, so that publication of an extended abstract in TARK will not prejudice publication of a full journal version. TARK 2013 will precede the Indian Conference on Logics and Applications (ICLA) held from January 10 - 12, 2013, also at the Institute of Mathematical Sciences in Chennai, India. TARK 2013 is the 14th conference of the TARK conference series. Previous conferences have been held bi-annually around the world. The most recent conference was held 2011 at the University of Groningen, Netherlands, see http://www.philos.rug.nl/TARK2011/. The proceedings of all previous TARK conferences can be accessed here http://www.tark.org/ TARK 2013 is the first TARK conference to be held in India. It is also the first TARK conference to be held in January. Key Dates for TARK 2013 Submission of abstracts: September 3, 2012 Notification of authors: October 29, 2012 Camera ready copy of accepted papers: November 30, 2012 Conference: January 7 - 9, 2013, Institute of Mathematical Sciences, Chennai, India Program Committee Samson Abramsky, Oxford University Thomas Agotnes, Universitetet i Bergen Hans van Ditmarsch, Universidad de Sevilla Amanda Friedenberg, Arizona State University Aviad Heifetz, The Open University of Israel Jerome Lang, Université Paris-Dauphine and Université Paul Sabatier Fenrong Liu, Tsinghua University Larry Moss, Indiana University, Bloomington Antonio Penta, University of Wisconsin-Madison Andres Perea, Maastricht University R.
