Hopf Galois extensions

open access: yes, 2020
Let H be a Hopf algebra which coacts to the right on A and let B be the subalgebra of coinvariants. The extension B < A is said to be Hopf Galois if the canonical Galois map is a bijection. This work investigates this kind of extension for special coactions.
