Title: Computing fusion rules for G-extensions of fusion categories
Speaker: Marcel Bischoff (Ohio University)
Abstract: A G-graded extension of a fusion category C yields a categorical action of G by braided autoequivalences on the Drinfel'd center Z(C) of C. I will explain a method for recovering the fusion rules of the G-graded extension in terms of the above-mentioned categorical action. The goal is to discuss several examples which can be computed using this method.
Based on joint work in progress with Corey Jones.
