Simple-direct-projective modules
In this paper, we introduce and study the dual notion of simple-direct-injective modules.
Namely, a right R-module M is called simple-direct-projective if, whenever A and B are …

D3-Modules
M Yousif, I Amin, Y Ibrahim - Communications in Algebra, 2014 - Taylor & Francis
A right R-module M is called a D 3-module, if M 1 and M 2 are direct summands of M with M=
M 1+ M 2, then M 1∩ M 2 is a direct summand of M. Following the work of Bass on projective …

ABSTRACT A right R-module M is called a U-module if, whenever A and B are submodules
of M with A≅ B and A∩ B= 0, there exist two summands K and L of M such that A⊆ ess K …

[HTML][HTML] Rings and modules characterized by opposites of injectivity
In a recent paper, Aydoǧdu and López-Permouth have defined a module M to be N-

ABSTRACT A module M is said to be square free if whenever its submodule is isomorphic to
N 2= N⊕ N for some module N, then N= 0. Dually, a module M is said to be d-square free …
