$H_4$和$H_8$的双交叉产物

The bicrossed products of $H_4$ and $H_8$

Daowei Lu, Yan Ning, Dingguo Wang

摘要:

设$H_4$和$H_8$分别是Sweedler和Kac-Paljutkin霍普夫代数.本文证明了任何通过$H_8$和$H_4$分解的霍普夫代数(等价于任何两个Hopf霍普夫代数之间的双交叉积)必同构于下列四个Hopf代数之一:$H_8 \otimes H_4, H_{32,1}, H_{32,2}, H_{32,3}$ .给出了所有匹配对$(H_8, H_4, \triangleright, \triangleleft)$的集合的显式描述,并利用生成元和关系给出了相应的双交叉积.

英文摘要:

Let $H_4$ and $H_8$ be the Sweedler's and Kac-Paljutkin Hopf algebras, respectively. In this paper we prove that any Hopf algebra which factorizes through $H_8$ and $H_4$ (equivalently, any bicrossed product between the Hopf algebras $H_8$ and $H_4$) must be isomorphic to one of the following four Hopf algebras: $H_8 \otimes H_4, H_{32,1}, H_{32,2}, H_{32,3}$. The set of all matched pair $(H_8, H_4, \triangleright, \triangleleft)$ is explicitly described, and then the associated bicrossed products is given by generators and relations.
