Scope of the Conference

---------------------------------

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).

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

* Point-free topology

* Proofs and Types

* Residuated structures

* Semantics

* Stone-type dualities

* Substructural logics

* Topological semantics of modal logic

The Summer School

----------------------------

TACL brings together different disciplines with the goal of exploring problems in logic. Partly due to the success of the TACL conference series, researchers have started employing tools used outside their immediate areas, either individually or in collaboration with specialists in research fields featured in the series. Such interactions have also naturally lead to new directions that combine ideas from two or more research fields.

This has been a gradual and arduous process and TACL can boast of having participants that are at least somewhat familiar with most of the featured areas. However, young researchers and students who attend the conference and work in TACL fields have a more restricted and specialized repertoire of tools and knowledge. The goal of the Summer School is to fill the gap and expose such researchers to a variety of methods that can be used to study logic. It will primarily target graduate students and postdocs, but also more senior researchers who are not familiar with aspects of neighboring areas. 

Prospective Summer School participants should express their interest on the 'Express Interest' page of the TACL 2013 web site by selecting the events that plan to attend (summer school and/or conference). Limited funds for supporting summer school participants are available (mainly through NSF). Those who plan to request financial support should submit a copy of their CV and a letter of support from their PhD advisor or post-doc supervisor (if applicable) to [email protected] with 'Summer School support request' in the subject line by April 21, 2013. In addition, they need to fill out the financial support form on the 'Support Requests' page by the same date. Registration should also be completed by June 1, 2013. We would appreciate your assistance in advertising the Summer School to interested students. Additional information can be found on the 'Summer School' page of the TACL 2013 web site.

Submissions to the Conference

-------------------------------------------

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.
