小量子群的支撑簇与表示类型

Support varieties and representation type of small quantum groups

Joerg Feldvoss, Sarah Witherspoon

摘要:

本文给出了任意有限维霍普夫代数具有广义生成上同调的一个野性准则。这将Farnsteiner的一个结果推广到任意特征的基域上的不一定是余交换的霍普夫代数.我们的证明使用了模的支撑簇理论,其中一个关键因素是某些特殊模的张量积性质。作为应用,我们证明了Cibils的一个猜想:秩至少为2的小量子群是wild的.

英文摘要:

In this paper we provide a wildness criterion for any finite dimensional Hopf algebra with finitely generated cohomology. This generalizes a result of Farnsteiner to not necessarily cocommutative Hopf algebras over ground fields of arbitrary characteristic. Our proof uses the theory of support varieties for modules, one of the crucial ingredients being a tensor product property for some special modules. As an application we prove a conjecture of Cibils stating that small quantum groups of rank at least two are wild.
