报告题目:  

On twisted quantum doubles of finite groups and their exponents

 

摘要:

Given a finite group G and a 3-cocycle w of G, one can construct a quasitriangular quasi-Hopf algebra H, called the twisted quantum double of (G,w). The category H-mod of finite dimensional modules over H is a modular tensor category. However, two different pairs (G, w), and (G’, w’) may yield equivalent twisted quantum doubles, that means their representation categories are equivalent modular tensor categories. In this talk, we will discuss these twisted quantum doubles and their exponents.
