Title:  Graded extensions of generalized Haagerup categories 

Speaker:  Pinhas Grossman (UNSW)

Abstract:  There is an obstruction theory for graded extensions of fusion categories due to Etingof, Nikshych, and Ostrik. However, computing the obstructions can be difficult in concrete examples. In this talk we will discuss a direct construction of graded extensions of generalized Haagerup categories using operator algebras, which leads to a number of new examples of fusion categories. This is joint work with Masaki Izumi and Noah Snyder.
