Galois-type correspondences for Hopf Galois extensions

K-Theory, 1994
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.

GALOIS CORRESPONDENCES FOR PARTIAL GALOIS AZUMAYA EXTENSIONS

Journal of Algebra and Its Applications, 2011
Let α be a partial action, having globalization, of a finite group G on a unital ring R. Let Rα denote the subring of the α-invariant elements of R and CR(Rα) the centralizer of Rα in R. In this paper we will show that there are one-to-one correspondences among sets of suitable separable subalgebras of R, Rα and CR(Rα). In particular, we extend to the

Gradings of Galois Extensions

Journal of Mathematical Sciences
This paper deals with the gradings of finite field extensions in which all homogeneous components are one-dimensional. Such gradings are called \textit{fine}. Kummer extensions, obtained by adjoining roots of elements from the base field, admit a natural grading based on the Galois group, and all homogeneous components are one-dimensional in this case.
