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.
Keywords: essentially quasi-injective module, essentially endomorphism-extendable module, ADS-module, essentially Noetherian module.
