RD-flatness and RD-injectivity of simple modules

A Moradzadeh-Dehkordi, F Couchot - Journal of Pure and Applied Algebra, 2022 - Elsevier
We say that a ring R is a right RDV-ring if each simple right R-module is RD-injective. In this
paper, we study the notion of RDV-rings which is a non-trivial generalization of V-rings and …

Rings with flat left socle

L Zhongkui - Communications in Algebra, 1995 - Taylor & Francis
We recall that a study of rings with projective left socle and containing no infinite sets of
orthogonal idenlpotents was make by Gordon [7]. In the same paper he showed that S= SOC …

Modules and abelian groups with a bounded domain of injectivity

YM Demirci - Journal of Algebra and Its Applications, 2018 - World Scientific
In this work, impecunious modules are introduced as modules whose injectivity domains are
contained in the class of all pure-split modules. This notion gives a generalization of both …

Three questions on strongly п-regular rings and regular rings

W Xue - Communications in Algebra, 1993 - Taylor & Francis
Throughout this paper rings are associative rings with identity, ring extensions share the
same identity, and modules are unitary. We shall consider the following three questions that …

On homological dimensions of simple modules over non-commutative rings

H Zhao-Yong, C Fu-Chang - Communications in Algebra, 1996 - Taylor & Francis
It is known that for a simple module S over a commutative ring R, fd R (S)= id R (S). Let RT
be commutative rings and R→ T a ring homomorphism, if T is a Noetherian ring and self …

Gorenstein flatness and injectivity over Gorenstein rings

WL Song, ZY Huang - Science in China Series A: Mathematics, 2008 - Springer
Let R be a Gorenstein ring. We prove that if I is an ideal of R such that R/I is a semi-simple
ring, then the Gorenstein flat dimension of R/I as a right R-module and the Gorenstein …
