The commutator Hopf Galois extensions
Szeto, George; Xue, Lianyong
Let H be a finite dimentional Hopf algebra over
a field k and H* the dual Hopf algebra of H. Then a commutator
right H*-Galois extension B of BH is characterized in terms of the
smash product B#H and some relationships between such a B and
the Hopf Galois Azumaya or Hopf Galois Hirata extensions are also
given.
