Monoidal Category Approach to Dual Hom-quasi-Hopf Algebras

In this paper, we categorify a Hom-associative algebra by imposing the Homassociative law up to some isomorphisms on the multiplication map and requiring that these isomorphisms satisfy the Pentagon axiom, and obtain a 2-Hom-associative algebra. On the other hand, we introduce the dual Hom-quasi-Hopf algebra and show that any dual Homquasi-Hopf algebras can be viewed as a 2-Hom-associative algebra.

Hom-ω-smash积Hopf代数的拟三角结构

设(A,α)和(H,β)是Hom-双代数,ω:H(?)A→A(?)H是线性映射,定义了Hom-ω-smash积(A#_ωH,γ),并给出了(A(?)_ωH,γ)是Hom-bialgebra的充要条件.最后,研究了(A(?)_ωH,γ)上的拟三角结构,并给出了它是拟三角Hom-Hopf代数的充要条件.

The quasi-triangular structures over Hom-ω-smash coproduct Hopf algebras

Let （C,α） and （H, β） be Hom-bialgebras and ω ： C × H → H × C a linear map. We introduce a Horn-ω-smash coproduct （Cω H, γ） and give necessary and sufficient conditions for （Cω H, γ） to be a Hom-bialgebra. We study the quasi-triangular structures over （Cω H, γ） and show the necessary and sufficient conditions for （Cω H, γ R） to be a quasi-triangular Hom-Hopf algebra. As applications of our results, we introduce the concept of D（H）＊ and construct quasi-triangular structures over D（H）＊.

Hom-Hopf代数的对极和Drinfel’d偶

本文证明了带有等价Hom-范畴的Hom-双代数是Hom-Hopf代数,在基本结构定理成立的前提下,构造了对极使其成为Hom-Hopf代数.研究了拟三角Hom-Hopf代数的对极,并给出了Hom-Hopf代数的Radford公式.最后,对有限维Hom-Hopf代数,引入了Drinfel’d偶的概念,同时证明了Drinfel’d偶是拟三角Hom-Hopf代数.
