Correlators, topological field theory and categorification (2/3)

Tobias Dyckerhoff (U Hamburg)

Categorified state sums and the topological A-model: We begin with an elementary mathematical perspective on state sum constructions for correlators of the most basic kinds of 2D topological field theories. Taking this as a starting point, we will see how a categorified variant of these constructions somewhat surprisingly leads to a description of 2D Fukaya categories (in string theoretic terms, these are categories of branes in the topological A-model introduced by Witten). Time permitting, we will say a few general words about this novel type of categorification and what we would like to do with it.
