Comatrix Corings and Galois Comodules over Firm Rings
J. Gomez-Torrecillas, J. Vercruysse
We give a notion of a comatrix coring which embodies all former constructions and, what is more interesting, leads to the formulation of a notion of Galois coring and the statement…

Local units versus local projectivity. Dualisations: Corings with local structure maps
Joost Vercruysse
We unify and generalize different notions of local units and local projectivity. We investigate the connection between these properties by constructing elementary algebras from loc…

Galois theory for comatrix corings: descent theory, Morita theory, Frobenius and separability properties
S. Caenepeel, E. De Groot, J. Vercruysse
El Kaoutit and Gómez Torrecillas introduced comatrix corings, generalizing Sweedler's canonical coring, and proved a new version of the Faithfully Flat Descent Theorem. They also i…
