Clifford theory for cocentral extensions

Rings and Algebras 2009-01-13 v1 Quantum Algebra

Abstract

The classical Clifford correspondence for normal subgroups is considered in the more general setting of semisimple Hopf algebras. We prove that this correspondence still holds if the extension determined by the normal Hopf subalgebra is cocentral.
