Doi-Hopf modules and Yetter-Drinfeld modules for quasi-Hopf algebras

D. Bulacu, S. Caenepeel, B. Torrecillas

For a quasi-Hopf algebra , a left -comodule algebra $\mf{B}$ and a right -module coalgebra we will characterize the category of Doi-Hopf modules ${}^C{\cal M}(H)_{\mf{…

Factorizable quasi-Hopf algebras. Applications

Daniel Bulacu, Blas Torrecillas

We define the notion of factorizable quasi-Hopf algebra by using a categorical point of view. We show that the Drinfeld double of any finite dimensional quasi-Hopf algebra $…

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…

Two-sided (two-cosided) Hopf modules and Doi-Hopf modules for quasi-Hopf algebras

D. Bulacu, S. Caenepeel

Let be a finite dimensional quasi-Hopf algebra over a field and a right -comodule algebra in the sense of Hausser and Nill. We first show that on the

The quantum double for quasitriangular quasi-Hopf algebras

D. Bulacu, S. Caenepeeel

Let be the quantum double associated to a finite dimensional quasi-Hopf algebra . In this note, we first generalize a result of Majid, stating that a finite dimensional H…
