This is the first extensive treatment of the theory of corings and their comodules. In the first
part, the module-theoretic aspects of coalgebras over commutative rings are described …

Doi-Koppinen Hopf modules and entwined modules unify various kinds of modules that
have been intensively studied over the past decades, such as Hopf modules, graded …

We show, for an arbitrary adjunction F⊢ U: B→ A with B Cauchy complete, that the functor F
is comonadic if and only if the monad T on A induced by the adjunction is of effective …

The aim of this paper is to prove the statement in the title. As a by-product, we obtain new
globalization results in cases never considered before, such as partial corepresentations of …

The main aim of this paper is to give a Hopf algebroid approach to the Picard-Vessiot theory
of linear differential matrix equations with coefficients in the polynomial complex algebra. To …

The so called dense pairings were studied mainly by Radford in his work on coreflexive
coalegbras over fields. They were generalized in a joint paper with Gómez-Torricillas and …

We characterize the corings whose category of comodules has a generating set of small
projective comodules in terms of the (noncommutative) descent theory. In order to extricate …
