Frobenius properties and Maschke-type theorems for entwined modules
Tomasz Brzezinski
Abstract
Entwined modules arose from the coalgebra-Galois theory. They are a generalisation of unified Doi-Hopf modules. In this paper, Frobenius properties and Maschke-type theorems, known for Doi-Hopf modules are extended to the case of entwined modules.
