Frobenius and Mashke type Theorems for Doi-Hopf modules and entwined modules revisited: a unified approach

Tomasz Brzezinski, S. Caenepeel, G. Militaru +1

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 unif…
