Perfect monoids with zero and categories of -acts
Josef Dvořák, Jan Žemlička
In this paper, we study the relationship between the two main categories of -acts for a monoid with zero from the viewpoint of existence of projective covers and the equival…
Self-small products of abelian groups
Josef Dvořák, Jan Žemlička
For abelian groups , is called -small if the covariant functor commutes with all direct sums and is self-small provided it is -small. The p…
Autocompact objects of Ab5 categories
Josef Dvořák, Jan Žemlička
The aim of the paper is to describe autocompact objects in Ab5-categories, i.e. objects in cocomplete abelian categories with exactness preserving filtered colimits of exact sequen…
Connected objects in categories of -acts
Josef Dvořák, Jan Žemlička
In this paper, the categorial property of compactness of an object, i. e. commuting of the corresponding $\Hom$ functor with coproducts, is studied in categories of -acts and th…
