Essentially quasi-injective modules and their direct sums
https://doi.org/10.26907/0021-3446-2024-7-9-23
Abstract
Conditions are studied under which an arbitrary direct sum of essentially (quasi-) injective modules is an essentially (quasi-) injective module. A description of essentially quasi-injective Abelian groups is obtained.
