Global Gorenstein dimensions
D Bennis, N Mahdou - Proceedings of the American Mathematical Society, 2010 - ams.org
In this paper, we prove that the global Gorenstein projective dimension of a ring $ R $ is
equal to the global Gorenstein injective dimension of $ R $ and that the global Gorenstein …

Gorenstein FP-injective and Gorenstein flat modules
L Mao, N Ding - Journal of Algebra and Its Applications, 2008 - World Scientific
In this paper, Gorenstein FP-injective modules are introduced and studied. An R-module M
is called Gorenstein FP-injective if there is an exact sequence⋯→ E1→ E0→ E0→ E1→⋯ of …

FI-injective and FI-flat modules
L Mao, N Ding - Journal of Algebra, 2007 - Elsevier
Let R be a ring. A left R-module M (respectively right R-module N) is called FI-injective
(respectively FI-flat) if Ext1 (G, M)= 0 (respectively Tor1 (N, G)= 0) for any FP-injective left R …

On divisible and torsionfree modules
L Mao, N Ding - Communications in Algebra®, 2008 - Taylor & Francis
A ring R is called left P-coherent in case each principal left ideal of R is finitely presented. A
left R-module M (resp. right R-module N) is called D-injective (resp. D-flat) if Ext1 (G, M)= 0 …

Relative FP-injective modules and relative IF rings
F Wang, H Kim - Communications in Algebra, 2021 - Taylor & Francis
Let R be a commutative ring and w be the so-called w-operation on R. Then we introduce
and study two concepts of w-FP-injective modules and w-IF rings. To do so, we use two main …

A note on Gorenstein flat dimension
D Bennis - Algebra Colloquium, 2011 - World Scientific
Unlike the Gorenstein projective and injective dimensions, the majority of results on the
Gorenstein flat dimension have been established only over Noetherian (or coherent) rings …

On copure projective modules and copure projective dimensions
X Fu, H Zhu, N Ding - Communications in Algebra, 2012 - Taylor & Francis
Let R be any ring. A right R-module M is called n-copure projective if Ext1 (M, N)= 0 for any
right R-module N with fd (N)≤ n, and M is said to be strongly copure projective if Ext i (M, F) …
