Perfect monoids with zero and categories of $S$ -acts

Josef Dvořák, Jan Žemlička

In this paper, we study the relationship between the two main categories of $S$ -acts for a monoid $S$ 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 $A, B$ , $A$ is called $B$ -small if the covariant functor $H o m (A, -)$ commutes with all direct sums $B^{(κ)}$ and $A$ is self-small provided it is $A$ -small. The p…
