Comatrix Corings an Invertible Bimodules
L. El Kaoutit, J. Gomez-Torrecillas
We extend Masuoka's Theorem [11] concerning the isomorphism between the group of invertible bimodules in a non-commutative ring extension and the group of automorphisms of the asso…
Monoidal Categories of Corings
L. El Kaoutit
We introduce a monoidal category of corings using two different notions of corings morphisms. The first one is the (right) coring extensions recently introduced by T. Brzeziński in…
Infinite Comatrix Corings
L. El Kaoutit, J. Gomez-Torrecillas
We characterize the corings whose category of comodules has a generating set of small projective comodules in terms of the (non commutative) descent theory. In order to extricate t…
Comatrix corings: Galois corings, Descent Theory, and a Structure Theorem for Cosemisimple corings
L. El Kaoutit, J. Gomez-Torrecillas
In order to extrincate the structure of corings with a finitely generated and projective generator we give the notion of a comatrix coring. As consequences we give generalizations…
