Title: Group gradings and actions of pointed Hopf algebras

Abstract: Finite-dimensional pointed Hopf algebras with abelian groups of group-likes are generated by their group-like and skew primitive elements. This makes it possible to apply a well developed theory of group gradings on simple finite-dimensional associative algebras to the study of actions of a wide class of pointed Hopf algebras on these algebras.
