报告摘要: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. In this talk, we will discuss the exponent of H-mod and its associated representation of SL(2,Z).
