Topology, Algebra, and Categories in Logic 2019

Nice, June 17 - 21 (conference)

Île de Porquerolles, June 10 - 15 (school)

Background and scope of the conference. Studying logic 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 programme of the conference TACL 2019 will focus on three interconnecting mathematical themes central to the semantic study of logic and their applications: topological, algebraic, and categorical methods.

TACL 2019 is the ninth 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), Marseille (2011), Nashville (2013), Ischia (2015), and Prague (2017).

Topics. Contributed talks are intended to be about topological, algebraic or categorical methods which are used in mathematical or computer science logic. This includes, but is not limited to, the following areas:

Algebraic logic
Algebraic structures in CS
Categorical methods in logic
Coalgebra
Domain theory
