Weak uS-flat Modules and Dimensions

RAK Assaad, X Zhang - Kyungpook Mathematical Journal, 2023 - koreascience.kr
In this paper, we generalize the notions uniformly S-flat, briefly uS-flat, modules and
dimensions. We introduce and study the notions of weak uS-flat modules. An R-module M is …

On -copure flat modules and dimension

EM Bouba, M Tamekkante - 대한수학회보, 2020 - dbpia.co.kr
Let $ R $ be a commutative ring. An $ R $-module $ M $ is said to be $ w $-flat if $\Tor^{R} _

On --Flat modules and Their Homological Dimensions

X Zhang, W Zhao - arXiv preprint arXiv:2107.12643, 2021 - arxiv.org
In this paper, we introduce and study the class of $\phi $-$ w $-flat modules which are
generalizations of both $\phi $-flat modules and $ w $-flat modules. The $\phi $-$ w $-weak …

Let R be a commutative ring. An R-module M is called a semiregular w-flat module if TorR 1
(R/I, M) is GV-torsion for any finitely generated semi-regular ideal I. In this article, we show …

∏-COHERENT DIMENSIONS AND∏-COHERENT RINGS

L Mao - Journal of the Korean Mathematical Society, 2007 - koreascience.kr
R is called a right ${\Pi}-coherent $ ring in case every finitely generated torsion less right R-
module is finitely presented. In this paper, we define a dimension for rings, called ${\Pi} …
