Title: Categorical aspects of class S field theories
Abstract: In physics, there is an important class of quantum field theories whose properties are encoded in the geometry of Riemann surfaces. These are the theories of class S. In this lecture series, I will explain how some aspects of class S theories can be understood mathematically using triangulated categories. In particular, I will explain how this leads to categorifications of various interesting moduli spaces in low-dimensional geometry and topology.
