H-Galois extensions with normal basis for weak Hopf algebras
(International Electronic Journal of Algebra, 2017)
Let H be a weak Hopf algebra and let A be an H-comodule algebra with subalgebra of coinvariants AH. In this paper we introduce the notion of H-Galois extension with normal basis and we prove that AH ,→ A is an H-Galois ...
The group of strong Galois objects associated to a cocommutative Hopf quasigroup
(Korean Mathematical Society, 2017)
Let H be a cocommutative faithfully flat Hopf quasigroup in a strict symmetric monoidal category with equalizers. In this paper we introduce the notion of (strong) Galois H-object and we prove that the set of isomorphism ...
