[PDF][PDF] On some monic covers and epic envelopes
S Crivei, B Torrecillas - Arabian Journal for Science and Engineering, 2008 - academia.edu
We establish equivalent conditions under which every object in an Abelian category has a
monic X-cover and an epic X-envelope respectively, when X is a class of objects closed …

Some remarks about -projectives modules
V Gubitosi, R Parra - arXiv preprint arXiv:2409.08334, 2024 - arxiv.org
Let $ R $ be a ring. In\cite {MD4} Mao and Ding defined an special class of $ R $-modules
that they called\(FP_n\)-projective $ R $-modules. In this paper, we give some new …

L DUAN, W LI - Bulletin of the Malaysian Mathematical Society, 2014 - kurims.kyoto-u.ac.jp
Abstract In (n, d)-ring and n-coherent ring theory, n-presented modules plays an important
role. In this paper, we firstly give some new characterizations of n-presented modules and n …

Semidualizing modules and related modules
D Zhang, B Ouyang - Journal of Algebra and Its Applications, 2011 - World Scientific
In this paper, we prove that the Bass class with respect to a semidualizing bimodule C
contains all FP-injective S-modules. We introduce the definition of C-FP-injective modules …

(n, d)-Injective covers, n-coherent rings, and (n, d)-rings
W Li, B Ouyang - Czechoslovak Mathematical Journal, 2014 - Springer
It is known that a ring R is left Noetherian if and only if every left R-module has an injective
(pre) cover. We show that (1) if R is a right n-coherent ring, then every right R-module has an …
