Summary: | The notions of a "weak group entwining structure" and an "invertible weak group entwining structure" are introduced. Furthermore, the relationship between them and group corings is also investigated. It turns out that (weak) group entwining structures and (weak) group entwined modules can be viewed as group corings and comodules over group corings, respectively, which generalizes the recent work of Brzeziński (
2002
) and Brzeziński et al. (
2006
). |
