Abstract:
In this paper we characterize all Galois extensions over where is an arbitrary -Hopf order in . We conclude that the abelian group of -Galois extensions is isomorphic to a certain quotient of units groups in . This result generalizes the classification of -Galois extensions, where , due to Roberts, and also to Hurley and Greither.
