报告摘要：Let $(H,R)$ be a finite dimensional semisimple and cosemisimple quasi-triangular Hopf algebra over a field $k$. In this talk, by using the Majid's transmuted braided group of $H$ and Ostrik's theorem on characterizing module categories over monoidal categories, we present a structure theorem of irreducible objects of the Yetter-Drinfeld H-module category. The results generalize the structure of Yetter-Drinfeld modules over finite group algebras given byDijkgraaf-Pasquier-Roche and Gould.
