Abelian groups whose nonzero endomorphisms have nonessential kernels
(Journal of Algebra and its Applications, 2017)In this paper, we describe completely the -singular subgroup of an abelian group and a -nonsingular abelian group in terms of the basic subgroups of its p-components and the quotient group by the torsion part. We also prove ... -
Modules and abelian groups with minimal (pure-) projectivity domains
(Journal of Algebra and its Applications, 2017)In this paper, we give a complete description of the projectively poor abelian groups and prove that there exists a pure projectively poor abelian group. We show that over a commutative Artinian ring every module having a ...
