Abstract

Let (H,\aH)(H,\a_H) be a Hom-Hopf algebra, (A,\aA)(A,\a_A) a right HH-comodule algebra and (C,\aC)(C,\a_C) a left HH-module coalgebra. Then we have the category AM(H)C_A\mathcal{M}(H)^C of Hom-type Doi-Hopf modules. The aim of this paper is to make the category AM(H)C_A\mathcal{M}(H)^C into a braided monoidal category. Our construction unifies quasitriangular and coquasitriangular Hom-Hopf algebras and Hom-Yetter-Drinfeld modules. We study tensor identities for monoidal categories of Hom-type Doi-Hopf modules. Finally we show that the category AM(H)C_A\mathcal{M}(H)^C is isomorphic to A#CA\#C^*-module category.
