Research School: Topological Fukaya categories of surfaces with stops via gentle algebras
25th to 27th of August 2021
Gentle algebras are classical objects in the representation theory of associative algebra. Remarkably, they connect to many other areas of mathematics. In particular, in the context of homological mirror symmetry, the work in [Haiden-Katzarkov-Kontsevich 2017] and [Leikili-Polishchuk 2020] shows that the partially wrapped Fukaya category of a graded marked surface is triangle equivalent to the derived category of a homologically smooth graded gentle algebra with zero differential. In these lectures, we will give an overview of this result.
There will be six lectures over three days from 2-3pm (German time/UTC+2) and 3:15-4:15pm (German/UTC+2), followed by one research talk 4:30-5:20pm (German time/UTC+2) each day
