ON CORINGS AND COMODULES
It is shown that the categories of R-coalgebras for a commutative unital ring R and the category of A-corings for some R-algebra A as well as their respective categories of comodules are locally
Frobenius functors for corings
We investigate Frobenius pairs between categories of comodules over rather general corings. We particularize to the case of the adjoint pair of functors associated to a morphism of corings over
Comonads and Galois Corings
We investigate which aspects of recent developments on Galois corings and comodules admit a formulation in terms of comonads. The general theory is applied to the study of Galois comodules over
Group Corings
TLDR
Group corings are introduced, and functors between categories of comodules over group corings, and the relationship to graded modules over graded rings are studied, as well as Morita contexts associated to a group coring.
Adjoint and Frobenius Pairs of Functors for Corings
We investigate adjoint and Frobenius pairs between categories of comodules over rather general corings. We particularize to the case of the adjoint pair of functors associated to a morphism of
Comodules over semiperfect corings
We discuss when the Rat functor associated to a coring satisfying the left $\alpha$-condition is exact. We study the category of comodules over a semiperfect coring. We characterize semiperfect
SYMMETRY FOR COMODULE CATEGORIES
For coalgebras C over a field, we study when the categories of left C-comodules and of right C-comodules are symmetric categories, in the sense that there is a duality between the categories of
Compatibility Condition between ring and coring
We introduce the notion of bi-monoid in general monoidal category generalizing by this the notion of bialgebra. In the case of bimodules over a noncommutative algebra, we obtain a compatibility
Comatrix Corings and Galois Comodules over Firm Rings
We construct comatrix corings on bimodules without finiteness conditions by using firm rings. This leads to the formulion of a notion of Galois coring which plays a key role in the statement of a
Morita contexts and Galois theory for weak Hopf comodulelike algebras
We investigate the Morita context and graded cases for weak group corings and derive some equivalent conditions for µ to be surjective. Furthermore, we develop Galois theory for weak group corings.
