Let H be a finite dimensional Hopf algebra over a field
be the dual Hopf algebra of H, and
A be a left H-module algebra such that 
is a direct summand of A as an
An equivalent condition is given for an
Azumaya algebra A being an 
extension of 
and several characterizations of a general
Azumaya extension B with center
C are given in terms of the Azumaya smash product 
where B is called a general
Azumaya extension of 
if it is an extension (not necessarily separable) of
an Azumaya 
separable extensions, Hirata separable extensions, Azumaya algebras, Galois extensions, Hopf Galois extensions.
