AiML-2012: FINAL CALL FOR PAPERS 9-TH INTERNATIONAL CONFERENCE ON ADVANCES IN MODAL LOGIC COPENHAGEN, 22-25 AUGUST, 2012 http://hylocore.ruc.dk/aiml2012.html Advances in Modal Logic is an initiative aimed at presenting the state of the art in modal logic and its various applications. The initiative consists of a conference series together with volumes based on the conferences. Information about the AiML series can be obtained at http://www.aiml.net. AiML-2012 is the ninth conference in the series. TOPICS We invite submission on all aspects of modal logic, including: - history of modal logic - philosophy of modal logic - applications of modal logic - computational aspects of modal logic (complexity and decidability of modal and temporal logics, modal and temporal logic programming, model checking, model generation, theorem proving for modal logics) - theoretical aspects of modal logic (algebraic/categorical perspectives on modal logic, coalgebraic modal logic, completeness and canonicity, correspondence and duality theory, many-dimensional modal logics, modal fixed point logics, model theory of modal logic, proof theory of modal logic) - specific instances and variations of modal logic (description logics, modal logics over non-boolean bases, dynamic logics and other process logics, epistemic and deontic logics, modal logics for agent-based systems, modal logic and game theory, modal logic and grammar formalisms, provability and interpretability logics, spatial and temporal logics, hybrid logic, intuitionistic logic, substructural logics, computationally light fragments of all such logics) Papers on related subjects will also be considered. CONFERENCE LOCATION Advances in Modal Logic 2012 will be held at the IDA conference centre in downtown Copenhagen: http://ida.dk/sites/moedecenter/english/Sider/EnglishForside.aspx This is in easy walking distance from Copenhagen Central Station and a number of reasonably priced hotels. PAPER SUBMISSIONS There will be two types of submissions to AiML-2012: (1) Full papers for publication in the proceedings and presentation at the conference. (2) Abstracts for short presentation only. Both types of papers should be submitted electronically using the EasyChair submission page at http://www.easychair.org/conferences/?conf=aiml2012 At least one author of each accepted paper of abstract must register for, and attend, the conference to present his or her work. (1) FULL PAPERS. Authors are invited to submit, for presentation at the conference and publication in the proceedings, full papers reporting on original research and not submitted elsewhere. The proceedings of AiML'2012 will be published by College Publications (http://www.collegepublications.co.uk) in a volume to be made available at the conference. The submissions should be at most 15 pages, with an optional technical appendix of up to 5 pages, together with a plain-text abstract of 100-200 words. The submissions must be typeset in LaTeX, using a style file and template that will be provided on the AiML'2012 website. (2) ABSTRACTS. These should be at most 5 pages. They may describe preliminary results, work in progress etc., and will be subject to light reviewing. The accepted abstracts will be made available at the conference, and the authors will have the opportunity to make short presentations (of up to 15 minutes) on them. SPECIAL SESSION ON HYBRID LOGIC. Hybrid logic is an extension of modal logic allowing to refer explicitly to states of the model in the syntax of formulas. There will be a special session of AiML devoted to papers on hybrid logic. The scope of the special session is standard hybrid-logical machinery like nominals, satisfaction operators, and the downarrow binder, but also other extensions of modal logic can be considered. SPECIAL SESSION IN HONOUR OF LARISA MAKSIMOVA. There will be a special session of AiML devoted to papers and talks in honour of Larisa Maksimova, in recognition of her many outstanding contributions to modal logic. SPECIAL SESSION ON MODALITIES FOR TYPES. Recent years have witnessed significant growth of interest in constructive type-theoretical modalities, in particular modalities ensuring productivity and type safety of (co-)recursive definitions in reactive programming. Some earlier examples include the use of modalities for staged computation, metaprogramming or in computational lambda-calculus. In order to boost interaction between programming, type-theoretical and modal communities, AiML 2012 will host a special session on these topics. Papers for this session should be submitted to the EasyChair site along with others. Papers for the special sessions should be submitted to the EasyChair site along with others.

DICE 2012 - Call for Extended Abstracts
by Nao Hirokawa 09 Feb '12

09 Feb '12

皆様 ETAPS 2012 で非明示計算量に関するワークショップ DICE 2012 が行われます。その extended abstract 募集をご案内致します。このカテゴリは既発表の内容も投稿可能です。ETAPS 参加の方はぜひ投稿をご検討下さい。廣川 =============================================================== CALL FOR EXTENDED ABSTRACTS DICE 2012 3rd Workshop on Developments in Implicit Complexity Tallinn (Estonia), March 31st and April 1st, 2012 (Affiliated with ETAPS 2012) http://dice2012.cs.unibo.it/ =============================================================== SCOPE The area of Implicit Computational Complexity (ICC) has grown out from several proposals to use logic and formal methods to provide languages for complexity-bounded computation (e.g. polytime or logspace computation). It aims at studying computational complexity without referring to external measuring conditions or a particular machine model, but only by considering language restrictions or logical principles implying complexity properties. This workshop focuses on ICC methods related to programs (rather than descriptive methods). In this approach one relates complexity classes to restrictions on programming paradigms (functional programs, lambda calculi, rewriting systems), such as ramified recurrence, weak polymorphic types, linear logic and linear types, and interpretative measures. The two main objectives of this area are: * to find natural implicit characterizations of various complexity classes of functions, thereby illuminating their nature and importance; * to design methods suitable for static verification of program complexity. Therefore ICC is related on the one hand to the study of complexity classes, and on the other hand to static program analysis. The workshop will be open to contributions on various aspects of ICC including (but not exclusively): * types for controlling complexity, * logical systems for implicit computational complexity, * linear logic, * semantics of complexity-bounded computation, * rewriting and termination orderings, * interpretation-based methods for implicit complexity, * programming languages for complexity-bounded computation, * certification of complexity properties of programs, * application of implicit complexity to other programming paradigms (e.g. imperative or object-oriented languages). The first two DICE workshops were held in 2010 in Cyprus and in 2011 in Germany, both as part of ETAPS conferences. Before that, several meetings on this topic had already been held with success in Paris (WICC 2008), and Marseille (GEOCAL 2006 workshop on Implicit computational complexity). _______________________________________________________________ INVITED TALKS * Ulrich Schoepp (LMU Munich) Computation by Interaction for Structuring Resource Bounded Computation * Neelakantan R.

When formalizing this problem, Gurevich (1988), together with Blass, actually proposed a logic LFP_inv, which is a version of least fixed-point logic plus some additional invariance condition. Although they don't believe that LFP_inv captures PTIME, no proof was given. Later, in a work of Nash, Remmel, and Vianu (2005), it was shown that whether LFP_inv captures PTIME is equivalent to the parameterized complexity of a halting problem: input: A nondeterministic Turing machine M and a natural number n in unary. parameter: |M|, i.e., the size of M question: does M accept the empty input in at most n steps? Our recent work (2010-11) reveals that it is even equivalent to an open problem in proof complexity, i.e., whether there is a polynomial optimal proof system for the set TAUT of tautologies of propositional logic. In this talk, I will discuss all these equivalences and their extensions to some other complexity classes beside PTIME. It turns out that Levin's optimal inverters (1973) play a central role in the proofs. This is joint work with Joerg Flum.

確率モデル検査で著名な Marta Kwiatkowska先生(University of Oxford)のご講演の案内です。(2件あります。) === 日時: 2月15日(水) 15:30〜場所: 東京大学理学部7号館007 A Framework for Verification of Software with Time and Probabilities Marta Kwiatkowska, University of Oxford (joint work with Gethin Norman and David Parker) Quantitative verification techniques are able to establish system properties such as "the probability of an airbag failing to deploy on demand'' or "the expected time for a network protocol to successfully send a message packet''. In this paper, we describe a framework for quantitative verification of software that exhibits both real-time and probabilistic behaviour. The complexity of real software, combined with the need to capture precise timing information, necessitates the use of abstraction techniques. We outline a quantitative abstraction refinement approach, which can be used to automatically construct and analyse abstractions of probabilistic, real-time programs. As a concrete example of the potential applicability of our framework, we discuss the challenges involved in applying it to the quantitative verification of SystemC, an increasingly popular system-level modelling language. === 日時: 2月17日(金) 15:30〜場所: 東京大学理学部7号館007 Design and Analysis of DNA Strand Displacement Devices using Probabilistic Model Checking Marta Kwiatkowska, University of Oxford (joint work with Matthew Lakin, David Parker, Luca Cardelli and Andrew Phillips, to appear in Journal of the Royal Society Interface) Designing correct, robust DNA devices is difficult because of the many possibilities for unwanted interference between molecules in the system. DNA strand displacement has been proposed as a design paradigm for DNA devices, and the DSD programming language has been developed as a means of formally programming and analysing these devices to check for unwanted interference. We demonstrate, for the first time, the use of formal verification techniques, in particular model checking and probabilistic model checking, to analyse the correctness, reliability and performance of DNA devices during the design phase. We use the probabilistic model checker PRISM, in combination with the DSD language, to design and debug DNA strand displacement components and to investigate their kinetics. We show how our techniques can be used to identify design flaws and to evaluate the merits of contrasting design decisions, even on devices comprising relatively few inputs. We then demonstrate the use of these components to construct a DNA strand displacement device for approximate majority voting. Finally, we discuss some of the challenges and possible directions for applying these methods to more complex designs.

03 Feb '12

Asian Workshop on Philosophical Logic "Asian Workshop on Philosophical Logic" will be organized by Research Center for Integrated Science (RCIS), Japan Advanced Institute of Science and Technology (JAIST) and held at the Ishikawa Hightech Ceter near JAIST from 15th to 17th February, 2012. Our aim is to promote mutual understandings among researchers on logic working in Asian countries, and to establish closer collaborations in future. The scope of the Workshop will cover: philosophical logic, non-classical logics, algebraic logic, and their applications in computer science and cognitive science During the Workshop, we will have a special session of discussions on future collaborations, in particular on research, education and exchange of researchers in our region. We welcome your participation in both talks and special session.
