Yetter-Drinfeld-Long bimodules are modules
Daowei Lu, Shuanhong Wang
Let be a finite dimensional bialgebra. In this paper, we prove that the category of Yetter-Drinfeld-Long bimodules is isomorphic to the Yetter-Drinfeld category over the tensor…

More properties of Yetter-Drinfeld category over dual quasi-Hopf algebras
Daowei Lu, Xiaohui Zhang, Dingguo Wang
Let be a dual quasi-Hopf algebra. In this paper we will firstly introduce all possible categories of Yetter-Drinfeld modules over , and give explicitly the monoidal and brai…

Crossed product Hom-Hopf algebras and lazy 2-cocycle
Daowei Lu, Shuangjian Guo
Let $(H,\a)$ be a Hom-Hopf algebra and $(A,\b)$ be a Hom-algebra. In this paper we will construct the Hom-crossed product $(A\#_σH,\bø\a)$, and prove that the extension $A\subseteq…
