v3.3.5
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.
The lecture takes place at DESY, building 2a, seminar room 2. It is recommended to wear masks during the lecture and follow distance regulations. You may also follow the lecture via Zoom:
