Separable functors for the category of Doi–Hopf modules, applications
We prove a Maschke type theorem for the category of Doi–Hopf modules. In fact, we give
necessary and sufficient conditions for the functor that forgets the C-coaction to be …

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 …

The fundamental theorem and Maschke's theorem in the category of relative Hom-Hopf modules
Y Chen, Z Wang, L Zhang - Colloquium Mathematicum, 2016 - infona.pl
We introduce the concept of relative Hom-Hopf modules and investigate their structure in a
monoidal category $ 𝓗̃ (ℳ_ {k}) $. More particularly, the fundamental theorem for relative …

Total integrals for weak Doi–Koppinen data
Z Wang, Y Chen, L Zhang - Algebras and Representation Theory, 2013 - Springer
In this paper, we introduce the concept of total integrals in the case of weak Hopf algebras,
which is a generalization of the total integral introduced by Menini and Militaru. We give two …
