[TACL 2011] First call for papers
by Hiroakira Ono 21 Dec '10

21 Dec '10

= = = = = = = ======================================================================== TOPOLOGY, ALGEBRA AND CATEGORIES IN LOGIC (TACL 2011) = = = = = = = ======================================================================== 26-30 July 2011 Universités Aix-Marseille I-II-III, France http://www.lif.univ-mrs.fr/tacl2011/ Scope ----- 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 2011 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 fifth 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). 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 * Fuzzy and many-valued logics * Lattice theory * Lattices with operators * Modal logics * Non-classical logics * Ordered topological spaces * Ordered algebraic structures * Pointfree topology * Proofs and Types * Residuated structures * Semantics * Stone-type dualities * Substructural logics * Topological semantics of modal logic Submissions ----------- Contributed presentations will be of two types: 20 minutes long presentations in parallel sessions and featured, 30 minutes long, plenary presentations. The submission of an abstract of 1-4 pages is 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 is available on the conference website. Important dates --------------- April 18, 2011: Abstract submission deadline May 20, 2011: Notification to authors July 26-30, 2011: Conference Program Committee ----------------- Guram Bezhanishvili, New Mexico State University Petr Cintula, Academy of Sciences of the Czech Republic Thierry Coquand, University of Gothenburg Mai Gehrke, Radboud University, Nijmegen Silvio Ghilardi, Università degli Studi di Milano Rob Goldblatt, Victoria University, Wellington Martin Hyland, King's College, Cambridge Ramon Jansana, Universitat de Barcelona Achim Jung (PC co-chair), University of Birmingham Alexander Kurz, University of Leicester Yves Lafont, Université Aix-Marseille II Tadeusz Litak, University of Leicester Paul-André Melliès, CNRS Paris Diderot George Metcalfe, Universität Bern Nicola Olivetti, Université Aix-Marseille III Hiroakira Ono, Japan Advanced Institute of Science and Technology Luigi Santocanale, Université Aix-Marseille I Kazushige Terui, Kyoto University Costantine Tsinakis, Vanderbilt University Yde Venema (PC co-chair), University of Amsterdam Friedrich Wehrung, Université de Caen Michael Zakharyaschev, University of London More Information ---------------- If you have any queries please send them to the conference email address: tacl2011(a)lif.univ-mrs.fr Luigi Santocanale, Yves Lafont, Nicola Olivetti, TACL 2011 local organisers ============================================================

Prof. Olivier Danvy Lecture at NII Logic Seminar
by Makoto Tatsuta 09 Dec '10

09 Dec '10

Prof. Olivier Danvy Lecture at NII Logic Seminar Date: December 16, 2010, 14:00--16:00 Place: National Institute of Informatics, Room 2005 (20th floor) 場所: 国立情報学研究所 20階 2005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/introduce/access1-j.shtml) Speaker: Prof. Olivier Danvy (University of Aarhus) Title: Small-step and Big-step Aspects of Computation (A Walk in the Semantic Park) Abstract: On the one hand, there are the De Morgan laws: it is clear how to repeatedly apply them to put a proposition in, say, negational normal form, with many small computational steps. On the other hand, such a normal form can be obtained with one big computational step by recursive descent. On the second hand, there is the lambda-calculus: it is clear how to repeatedly apply its contraction rules to put a lambda-term in, say, weak-head normal form, if one exists, with many small computational steps. On the other hand, such a normal form can be obtained with one big computational step by recursive descent. On the third hand, there are also abstract machines: state transition systems that will obligingly yields normal forms as well, if they exist. There is no fourth hand in this talk: our goal is not to monkey with computation, but to demonstrate a profound structural unity in the various styles of semantic artifacts that have been proposed to specify computation: as a calculus with a reduction strategy, as a small-step system of proof rules, as a small-step system of reductions in contexts, as a small-step abstract machine, as a big-step abstract machine, as a continuation-passing big-step evaluation function, and as a direct-style big-step evaluation function. In the course of this talk, we will materialize this unity by using off-the-shelf program transformations to constructively inter-derive semantic artifacts for deterministic sequential programming languages, or, to be precise, their representation as functional programs. 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

Trends in Logic IX Conference - first announcement
by Suzuki, Nobu-Yuki 02 Dec '10

02 Dec '10

皆さま静岡大学理学部数学科の鈴木信行と申します。以下のような案内が来ましたので、お知らせします。重複して受け取られた方には、ご寛恕をお願いいたします。 ---------------------------------------------------------------- Studia Logica International Conference Church's Thesis: Logic, Mind and Nature Krakow, Poland, June 3-5, 2010 http://StudiaLogica.org/TrendsIX contact: trendsIX(a)upjp2.edu.pl FIRST ANNOUNCEMENT Conference goals: In 1935 Alonzo Church formulated a thesis called, after Kleene, the Church's Thesis (CT). The acceptance of the CT led to a negative answer to Hilbert's Entscheindungsproblem. Since then, many important logicians and philosophers have ventured to solve the numerous problems connected to the CT. The problems include attempts at a proof of the CT, analysis of its status and its logical value, etc. These various lines of research have shown that the CT has many incarnations and constitutes an interdisciplinary problem. The research concerning the CT, as well as an analogical thesis developed by Alan Turing, has resulted in important insights regarding the concept of computability. Georg Kreisel formulated three versions of the CT, pertaining to machine, human, and physical computability. With respect to this, the conference's focus will be on three areas connected to the CT: logic, mind and nature. The main goals of the conference include the discussion over the major results concerning the CT, as well as the presentation of contemporary approaches to problems connected with the CT. Call for papers: We invite contributions pertaining to issues which lie in the fields for which the CT is an important problem. Especially, but not exclusively, we invite contributions related to: (A)Perspectives on Church's Thesis: history of the Church's Thesis; Church's Thesis and Turing's Thesis; pro and contra: arguments in the discussions concerning the CT; (B)Church's thesis and logic: definitions of the concept of algorithm, attempts at formalizing the CT, CT in constructivism, CT in epistemic mathematics, modal logics and the CT, functional programming and the CT, logical theory of concepts; (C)Church's Thesis and the mind: cognitivist approaches to the mind; theories of concepts; mind and computability; (D) Church's Thesis and nature: analog computations, computations by physical systems. Invited speakers: Jack Copeland (University of Canterbury), Marie Duzi (VSB-Technical University of Ostrava), Yuri Gurevich (University of Michigan), Petr Hajek (Academy of Sciences of the Czech Republic), Pavel Materna (Academy of Sciences of the Czech Republic), David McCarty (Indiana University), Wilfried Sieg (Carnegie Mellon University), Oron Shagrir (Hebrew University of Jerusalem), Stewart Shapiro (Ohio State University), Jan Wolenski (Jagiellonian University), Ryszard Wojcicki (Institute of Philosophy and Sociology, Polish Academy of Sciences), Konrad Zdanowski (Paris Diderot University). Some of the invited speakers have not confirmed their participation yet. Organizing Committee: Adam Olszewski (Chairman), Bartosz Brozek, Jacek Malinowski, Piotr Urbanczyk, Malgorzata Drozdz. Program Committee: Jacek Malinowski (Chairman), Heinrich Wansing, Hannes Leitgeb, Leon Horsten, Adam Olszewski. Organizers: Studia Logica, Copernicus Center for Interdyscyplinary Studies, Pontifical University of John Paul II in Cracow. Deadline: Please send an abstract not exceeding 2 pages to atolszad(a)cyf-kr.edu.pl not later than March 15. The authors will be notified about the acceptance of their papers within 4 weeks after submission. More details will be provided in the second announcement, which is to be distributed in the middle of February, 2011. On behalf of the Organizing Committee Adam Olszewski
