On n-Weak Cotorsion Modules
C Selvaraj, P Prabakaran - Lobachevskii Journal of Mathematics, 2018 - Springer
Let R be a ring and na fixed non-negative integer. In this paper, n-weak cotorsion modules
are introduced and studied. A right R-module N is called n-weak cotorsion module if Ext …

[PDF][PDF] On Gorenstein cotorsion dimension over GF-closed rings
Z Gao - Bulletin of the Korean Mathematical Society, 2014 - researchgate.net
In this article, we introduce and study the Gorenstein cotorsion dimension of modules and
rings. It is shown that this dimension has nice properties when the ring in question is left GF …

On FI-cotorsion modules and dimensions
AD Alqahtani, K Ouarghi - J. Math. Comput. Sci., 2021 - scik.org
In this paper we study the class of FI-cotorsion modules and we introduce there dimensions
of modules and rings. An R-module M is called FI-cotorsion if Ext 1 R (F, M)= 0 for any FI-flat …
