Fusion subcategories of Rep(D^{ω}(G)) 

Abstract: We will begin by briefly discussing the notions of fusion category, braided category, and modular category. Then we will consider the modular category arising from the twisted Drinfeld double of a finite group. We will describe all fusion subcategories of this category. As a consequence, we obtain a description of all grouptheoretical braided fusion categories. This talk is based on a joint work with D. Nikshych and S. Witherspoon.
