Rings whose quasi-injective modules are injective
KA Byrd - Proceedings of the American Mathematical Society, 1972 - ams.org
A ring R is called a V-ring, respectively SSI-ring, respectively QII-ring if simple, respectively
semisimple, respectively quasi-injective, right R-modules are injective. We show that R is …

[HTML][HTML] Virtually uniserial modules and rings
M Behboodi, A Moradzadeh-Dehkordi, MQ Nejadi - Journal of Algebra, 2020 - Elsevier
We study the class of virtually uniserial modules and rings as a nontrivial generalization of
uniserial modules and rings. An R-module M is virtually uniserial if for every finitely …

Generalized V-rings
VS Ramamurthi, KM Rangaswamy - Mathematica Scandinavica, 1972 - JSTOR
Kaplansky [11] noticed that a commutative ring is (von Neumann) regular if and only if it is a
V-ring, that is, each simple module over the ring is injective. However in the general case …

Certain overrings of right hereditary, right Noetherian rings are 𝑉-rings
F Hansen - Proceedings of the American Mathematical Society, 1975 - ams.org
It will be shown that a particular quotient ring of a ring $ R $ is a nontrivial $ V $-ring if $ R $
is a special kind of a right hereditary, right Noetherian ring. Another result states that all …

[PDF][PDF] On simple singular AP-injective modules
Z Yu-e - International Mathematical Forum, 2011 - Citeseer
In this paper, we investigate some properties of rings whose simple (singular) right R−
