论文摘要
我们对具有特征性零的代数闭合字段k进行了离散核心呈现类型的尖角代数。对于此类代数$ h $,我们明确确定代数结构为链接不可兼容的组件$ b $包含该单元的同构。事实证明,$ h $是$ b $和某个集团代数的交叉产品。
We classify pointed Hopf algebras of discrete corepresentation type over an algebraically closed field K with characteristic zero. For such algebras $H$, we explicitly determine the algebra structure up to isomorphism for the link indecomposable component $B$ containing the unit. It turns out that $H$ is a crossed product of $B$ and a certain group algebra.
