Talk at the Coalgebra Day 2010 in Amsterdam
Wednesday, 24 February 2010 09:12

The Coalgebra Day is an annual informal meeting of researchers in coalgebra between academic institutions in the Netherlands. This years meeting is held in Amsterdam and organised by Yde Venema, Vincenzo Ciancia, and Raul Leal.

At this meeting I will give a talk on my recent work on infinite trace semantics of coaglebras with branching and transition type. The work extends my previous work with Alexander Kurz on generic trace logics and generalises previous work of Bart Jacobs on trace semantics of coalgebras.

Talk on TQFTs and Quantum Invariants of 3-Manifolds at Warsaw
Sunday, 14 February 2010 14:06

On 27th February I will give an invited seminar in the TQFT study group at the University of Warsaw, in which I will discuss a construction of a 3-dimensional topological quantum field theory (3D-TQFT) in terms of modular functors, from which we obtain a theory of quantum invariants of 3-manifolds with embedded banded links.

From 06 to 09 December 2009 there will be a workshop on coalgebraic logic at Schloss Dagstuhl. The event is organised by Alexander Kurz and Ernst-Erich Doberkat. At the workshop I will give a talk on my work with Alexander on finite trace semantics and finite trace logics of coalgebras with branching type given by a monad.
