Remarks on fp-Injective and fp-Flat Modules

L Mao - Arabian Journal for Science and Engineering, 2011 - Springer
Abstract A left R-module M is said to be fp-injective if, for every monomorphism K→ L with K
and L finitely presented left R-modules, Hom (L, M)→ Hom (K, M) is an epimorphism. A right …

Rings for which every cosingular module is projective

Y Talebi, ARM Hamzekolaee… - Hacettepe Journal of …, 2019 - dergipark.org.tr
Let R be a ring and M be an R-module. In this paper we investigate modules M such that
every (simple) cosingular R-module is M-projective. We prove that every simple cosingular …
