Under study are the dual automorphism-invariant modules and pseudoprojective modules.
Some conditions were found under which the dual automorphism-invariant module over a …

A right module A over a ring R is called finitely injective if every diagram of right R-modules
of the form where X is finitely generated and the row is exact, can be imbedded in a …

The characterization of rings R by properties of the category of left R-modules can be
extended to the investigation of R-modules M by the study of the category a [M] …

Let $ R $ be the quotient of a regular coherent commutative ring by a finitely generated
ideal. In this paper, we classify all abelian subcategories of finitely presented $ R $-modules …
