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, tool and techniques stemming from various fields, including universal algebra, topology, category theory, order, and model theory. The program of the conference TACL 2015 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 seventh conference in the series Topology, Algebra and Categories in Logic (TACL, formerly TANCL). Earlier instalments of this conference have been organized in Tbilisi (2003), Barcelona (2005), Oxford (2007), Amsterdam (2009), Marseilles (2011), and Nashville (2013).


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
