Abstract :
[en] This paper extends Hopf-Galois theory to infinite field extensions and
provides a natural definition of subextensions. For separable (possibly
infinite) Hopf-Galois extensions, it provides a Galois correspondence. This
correspondence also is a refinement of what was known in the case of finite
separable Hopf-Galois extensions.
