Four-angle Hopf modules for Hom-Hopf algebras

Xiaoqian Liu, Dongdong Yan, Xuchen Deng +1

In this paper, we introduce the notion of a four-angle Hopf module for a Hom-Hopf algebra $(H, β)$ and show that the category $_{H}^{H} M_{H}^{H}$ of four-angle Hopf mod…

The Drinfel'd codouble constuction for monoidal Hom-Hopf algebra

Dongdong Yan, Shuanhong Wang

Let $(H, β)$ be a monoidal Hom-Hopf algebra with the bijective antipode $S$ , In this paper, we mainly construct the Drinfel'd codouble $T(H)=(H^{op}\otimes H^{*}, β\otimes β^{*-1})…
