Query: Frobenius and Mashke type Theorems for Doi-Hopf modules and entwined
  modules revisited: a unified approach   We study when induction functors (and their adjoints) between categories of
Doi-Hopf modules and, more generally, entwined modules are separable, resp.
Frobenius. We present a unified approach, leading to new proofs of old results
by the authors, as well as to some new ones. Also our methods provide a
categorical explanation for the relationship between separability and Frobenius
properties.
