Topology, Algebra, and Categories
in Logic
Prague, June 26–30


Organized by

Institute of Computer Science, Czech Academy of Sciences
Faculty of Arts, Charles University


Background and 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, tool and techniques stemming from various fields, including universal algebra, topology, category theory, order, and model theory. The programme of the conference TACL 2017 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 eight 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), Marseille (2011), Nashville (2013) and Ischia (2015).

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 Lattices with operators Proofs and types
Algebraic logic Modal logics Residuated structures
Coalgebra Non-classical logics Semantics
Categorical methods in logic Ordered topological spaces Stone-type dualities
Domain theory Ordered algebraic structures Substructural logics
Fuzzy and many-valued logics Pointfree topology Topological semantics of modal logic
Lattice theory

For additional accommodation options in Olomouc see eg. this page .

Student support

TACL school and TACL conference are sponsored by the Association for Symbolic Logic. This means that students can apply to the ASL for travel awards. Please refer to this page for information on how to do it. Applications must reach the ASL office before the 26th of March.

Full and partial support concerning TACL school registration, lunches and accommodation will be offered for selected students during the early registration period. You can apply for it during the registration process, and after a selection process based on merits and motivations, shortly after the early registration deadline you will be notified the kind of support you were assigned and the payment information to conclude the registration.
