Pointed Hopf Algebras of Discrete Corepresentation Type
Abstract
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.
