====================================================== TOPOLOGY, ALGEBRA AND CATEGORIES IN LOGIC (TACL 2013) ====================================================== July 28 - August 1, 2013 Department of Mathematics, Vanderbilt University Nashville, Tennessee USA http://www.math.vanderbilt.edu/~tacl2013/ The Sixth International Conference on Topology, Algebra and Categories in conjunction with the 28th Annual Shanks Lecture Series

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 2013 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 sixth 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), Marseilles (2011).

Confirmed invited speakers ------------------------------------- Vladimir Voevodsky, Institute for Advanced Studies, USA (Shanks Lecturer) Nick Bezhanishvili, Utrecht University, The Netherlands Leo Cabrer, University of Oxford, UK Silvio Ghilardi, University of Milan, Italy George Metcalfe, University of Bern, Switzerland Alex Simpson, University of Edinburgh, UK

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 * Lattice theory * Lattices with operators * Many-valued and fuzzy logics * 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: o 20 minutes long presentations in parallel sessions and o featured, 30 minutes long, plenary presentations. The submission of an abstract will be 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, as well as a link to the EasyChair system, can be found at the conference web site.
