More properties of Yetter-Drinfeld modules over quasi-Hopf algebras
D. Bulacu, S. Caenepeel, F. Panaite
We generalize various properties of Yetter-Drinfeld modules over Hopf algebras to quasi-Hopf algebras. The dual of a finite dimensional Yetter-Drinfeld module is again a Yetter-Dri…

Yetter-Drinfeld categories for quasi-Hopf algebras
D. Bulacu, S. Caenepeel, F. Panaite
We show that all possible categories of Yetter-Drinfeld modules over a quasi-Hopf algebra are isomorphic. We prove also that the category $\yd^{\rm fd}$ of finite dimensional l…
