报告摘要:Group-theoretical fusion category, which can be characterized by finite groups and cocycles, is an important class of fusion categories. In this talk, I will talk about the group-theoretical property of some non-degenerate fusion categories and applications in classifying factorizable semisimple Hopf algebras. We show that an integral nondegenerate fusion category C is group-theoretical if the Frobenius-Perron dimensions of its simple objects are either 1 or powers a prime p. As an application, we obtain structure conclusions of some semisimple factorizable (quasi-)Hopf algebras.
