[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 …

[PDF][PDF] Relative projective dimensions
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 …

内射模和投射模的推广
李煜彦, 何东林 - 兰州理工大学学报, 2011 - cqvip.com
设R 是环, n 和d 是固定的非负整数, T 是1-倾斜R-模(未必有限生成). 称R-模M 是(n, d)-T-内射模,
如果对任意P∈ Pr esn T, 有ExtdR+ 1 (P, M)= 0. 称R-模M 是(n, d)-T-投射模, 如果对任意(n, d)-T …

(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 …
