Hom-霍普夫代数的Drinfel'd Double与Heisenberg Double

The Drinfel'd Double versus the Heisenberg Double for Hom-Hopf Algebras

Daowei Lu, Shuanhong Wang

摘要:

设$(A,α)$是有限维Hom-霍普夫代数.本文主要通过两种方法在Hom- Hopf代数的背景下构造Drinfel'd double $D(A)=(A^{op}\bowtie A^{\ast},α\otimes(α^{-1})^{\ast})$,一种是推广了Majid关于Hopf代数的双交叉积(见\cite{M2}),另一种是引入Hom-霍普夫代数的对偶对的概念.然后研究了Drinfel的双$D(A)$与Heisenberg的双$H(A)=A\# A^{*}$之间的关系,推广了\cite{Lu}中的主要结果。特别地,文中给出的例子不是从通常的霍普夫代数中得到的.

英文摘要:

Let $(A,α)$ be a finite-dimensional Hom-Hopf algebra. In this paper we mainly construct the Drinfel'd double $D(A)=(A^{op}\bowtie A^{\ast},α\otimes(α^{-1})^{\ast})$ in the setting of Hom-Hopf algebras by two ways, one of which generalizes Majid's bicrossproduct for Hopf algebras (see \cite{M2}) and another one is to introduce the notion of dual pairs of of Hom-Hopf algebras. Then we study the relation between the Drinfel'd double $D(A)$ and Heisenberg double $H(A)=A\# A^{*}$, generalizing the main result in \cite{Lu}. Especially, the examples given in the paper are not obtained from the usual Hopf algebras.
