Finitistic dimension and restricted injective dimension
D Wu - Czechoslovak Mathematical Journal, 2015 - Springer
We study the relations between finitistic dimensions and restricted injective dimensions. Let
R be a ring and T a left R-module with A= End RT. If RT is selforthogonal, then we show that …

Strongly Gorenstein flat and Gorenstein FP-injective modules
C Yang - Turkish Journal of Mathematics, 2013 - journals.tubitak.gov.tr
In this paper, we first study the properties of strongly Gorenstein flat (resp. Gorenstein FP-
injective) modules which are special Gorenstein projective (resp. Gorenstein injective) …

Injective modules with respect to modules of projective dimension at most one
S Bouchiba, M El-Arabi - International Electronic Journal of Algebra, 2019 - dergipark.org.tr
Several authors have been interested in cotorsion theories. Among these theories we figure
the pairs $(\mathcal P_n,\mathcal P_n^{\perp}) $, where $\mathcal P_n $ designates the set …

On weak-injective modules over integral domains
L Fuchs, SB Lee - Journal of Algebra, 2010 - Elsevier
We show that a weak-injective module over an integral domain need not be pure-injective
