Foxby equivalence relative to $C$ - $f p_{n}$ -injective and $C$ - $f p_{n}$ -flat modules

Mostafa Amini, Alireza Vahidi, Farideh Rezaei

Let $R$ and $S$ be rings, $C =_{S} C_{R}$ a (faithfully) semidualizing bimodule, and $n$ a positive integer or $n = \infty$ . In this paper, we introduce the concepts of $C$ - $f p_{n}$ -injec…

Rings with finite n-Weak injective dimension and (n,k)-Weak cotorsion modules

Mostafa Amini, Houda Amzil, Driss Bennis

Let R be a ring and n,k be two non-negative integers. As an extension of several known notions, we introduce and study (n,k)-weak cotorsion modules using the class of right R-modul…

Category of n-weak injective and n-weak flat modules with respect to special super presented modules

Mostafa Amini, Houda Amzil, Driss Bennis

Let $R$ be a ring and $n$ , $k$ two non-negative integers. In this paper, we introduce the concepts of $n$ -weak injective and $n$ -weak flat modules and via the notion of special sup…

Finite unitary rings with a single subgroup of prime order of the group of units

Mostafa Amini, Mohsen Amiri

Let R be a unitary ring of finite cardinality P^k, where p is a prime number and $p ∤ k$ . We show that if the group of units of $R$ has at most one subgroup of order $p$ , then $…

n-gr-Coherent rings and Gorenstein graded modules

Mostafa Amini, Driss Bennis, Soumia Mamdouhi

Let R be a graded ring and n > 1 an integer. In this paper, We introduce the notions of Ding n-gr-injective and Ding n-gr-flat modules by using of special finitely presented graded…

Gorenstein n-X-injective and n-X-flat modules with respect to a special finitely presented module

Mostafa Amini, Arij Benkhadra, Driss Bennis

Let R be a ring, X a class of R-modules and n>1 an integer. In this paper, via special finitely presented modules, we introduce the concepts of Gorenstein n-X-injective and n-X-fla…
