S. Raianu: External Homogenization for Hopf Algebras: a Coring Point of View, p.369-375

Abstract:

We give a coring version for the external homogenization for Hopf algebras, which is a generalization of a construction from graded rings, called the group ring of a graded ting. We also provide a coring version of a Maschke-type theorem.

Key Words: Hopf algebra, Galois coring, crossed product, coseparable coring, separable functor.
