Call for Papers Special Issue of Information and Computation on Intuitionistic Modal Logics and Applications (IMLA) Guest Editors: Valeria de Paiva, Brigitte Pientka and Aleks Nanevski Submission deadline: 31. May, 2009 Constructive modal logics and type theories are of increasing foundational and practical relevance in computer science. Applications are in type disciplines for programming languages, and meta-logics for reasoning about a variety of computational phenomena. Theoretical and methodological issues center around the question of how the proof-theoretic strengths of constructive logics can best be combined with the model-theoretic strengths of modal logics. Practical issues center around the question of which modal connectives with associated laws or proof rules capture computational phenomena accurately and at the right level of abstraction and how to implement these efficiently. There have been a series of LICS-affiliated workshops devoted to the theme. The first one was held as part of FLoC1999, Trento, Italy, the second was part of FLoC2002, Copenhagen, Denmark, the third was associated with LiCS2005, Chicago, USA and the last one was associated with LICS 2008 in Pittsburgh, PA, USA. Two special issues of journals on the theme have already appeared, a Mathematical Structures in Computer Science volume edited by Matt Fairtlough, Michael Mendler and Eugenio Moggi ( Modalities in type theory) in 2001, and a special issue of the Journal of Logic and Computation in 2004 (Intuitionistic Modal Logics and Application, eds. Valeria de Paiva, R. Gore ad M. Mendler). We are hereby soliciting papers for a further special volume of Information and Computation, devoted to Intuitionistic Modal Logics and Applications. We hope to cover the novel applications presented in the last two workshops, especially applications to computer security, automated deduction and computational linguistics, but also to include work not presented at the workshops. The proposed timeline of events is as follows: * Papers (preferably under 20 pages long) should be submitted by 31st May 2009 * Reviews will be provided until the end of August 2009 and the volume should be ready by the end of the Fall. Topics of interest include, but are not limited to: * applications of intuitionistic necessity and possibility * monads and strong monads * constructive belief logics and type theories * applications of constructive modal logic and modal type theory to formal verification, foundations of security, abstract interpretation, and program analysis and optimization * modal types for integration of inductive and co-inductive types, higher-order abstract syntax, strong functional programming * models of constructive modal logics such as algebraic, categorical, Kripke, topological, and realizability interpretations * notions of proof for constructive modal logics * extraction of constraints or programs from modal proofs * proof search methods for constructive modal logics and their implementations. Please contact one of the editors (Valeria de Paiva valeria@cuill.com or Brigitte Pientka bpientka@cs.mcgill.ca) if you're not sure that your paper is within the scope of this special volume. Submissions should be 10 to 20 pages long and sent in PostScript or PDF format to one of the editors, before the 31st May 2009.
