On the classification of finite-dimensional pointed Hopf algebras
We classify finite-dimensional complex Hopf algebras A which are pointed, that is, all of whose irreducible comodules are one-dimensional, and whose group of group-like elements G.A/ is abelian such that all prime divisors of the order of G.A/ are > 7. Since these Hopf algebras turn out to be deformations …
