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 ring with minimal non-nilpotent group of units

Mohsen Amiri, Mostafa Amini

Let $R$ be a finite unitary ring such that $R = R_{0} [R^{*}]$ where $R_{0}$ is the prime ring and $R^{*}$ is not a nilpotent group. We show that if all proper subgroups of $R^{*}$ are nilpoten…
