Galois-type correspondences for Hopf Galois extensions
Copyright policy )Galois-type correspondences for Hopf Galois extensions
The authors construct a certain Hopf algebra associated with a commutative Galois extension in order to obtain a Galois correspondence between intermediate subalgebras of a Hopf-Galois extension and corresponding Hopf subalgebras.
