On strongly --Flat modules and Their Homological Dimensions

W Qi, X Zhang, W Zhao - arXiv preprint arXiv:2302.00991, 2023 - arxiv.org
In this paper, we introduce and study the notion of strongly $\phi $-$ w $-flat modules. The
$\phi $-$ w $-weak global dimension $\phi $-$ w $-w. gl. dim $(R) $ of an NP-ring $ R $ is …

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 …

Strongly -flat modules, strongly nonnil-injective modules and their homological dimensions

--projective modules and dimension

RAK Assaad, EM Bouba, M Tamekkante - arXiv preprint arXiv:2206.03533, 2022 - arxiv.org
Let $ R $ be a ring. An $ R $-module $ M $ is said to be an absolutely $ w $-pure module if
and only if $\Ext^ 1_R (F, M) $ is a GV-torsion module for any finitely presented module $ F …

On -(weak) global dimension

Y El Haddaoui, N Mahdou - Journal of Algebra and Its Applications, 2024 - World Scientific
In this paper, we will introduce and study the homological dimensions defined in the context
of commutative rings with prime nilradical. So all rings considered in this paper are …

[PDF][PDF] A HOMOLOGICAL CHARACTERIZATION OF Q0-PvMRS

[PDF][PDF] On w-copure flat modules and dimension

HK El Mehdi Bouba, M Tamekkante - Bull. Korean Math. Soc, 2020 - academia.edu
Let R be a commutative ring. An R-module M is said to be w-flat if Tor R 1 (M, N) is GV-
torsion for any R-module N. It is known that every flat module is w-flat, but the converse is not …

Weak injective and weak flat modules

Z Gao, F Wang - Communications in Algebra, 2015 - Taylor & Francis
Let R be a ring. A left R-module M (resp., right R-module N) is called weak injective (resp.,
weak flat) if (resp.,) for every super finitely presented left R-module F. By replacing finitely …
