秩为二的有限根系群上的Nichols代数(II)

Nichols algebras over groups with finite root system of rank two II

I. Heckenberger, L. Vendramin

摘要:

我们对所有非阿贝尔群G进行分类,使得存在G上的一对(V,W)绝对单Yetter-Drinfeld模,使得V与W的直和的Nichols代数在两个假设下是有限维的:V与W的辫的平方不是单位元,G由V与W的支集生成.作为推论,我们证明了这样的V和W的维数至多为6。作为一个工具,我们使用(V,W)的Weyl广群。

英文摘要:

We classify all non-abelian groups G such that there exists a pair (V,W) of absolutely simple Yetter-Drinfeld modules over G such that the Nichols algebra of the direct sum of V and W is finite-dimensional under two assumptions: the square of the braiding between V and W is not the identity, and G is generated by the support of V and W. As a corollary, we prove that the dimensions of such V and W are at most six. As a tool we use the Weyl groupoid of (V,W).
