Reversible ring property via idempotent elements

Georgian Mathematical Journal, 2022
Regarding the question of how idempotent elements affect the reversible property of rings, we study a version of reversibility depending on idempotents. In this perspective, we introduce right (resp., left) e-reversible rings.

On weakly reversible rings and strongly reversible rings

Publicationes Mathematicae Debrecen, 2010
The authors introduce the following class of rings which contains all commutative and all reduced rings: a ring \(R\) is called weakly reversible if \(ab=0\) implies the existence of \(x,y,z\in R\) such that \(xbyaz\) is a nilpotent element. In the paper the behaviour of weakly reversible rings under diverse constructions is studied.

I-Reversible rings

Journal of Algebra and Its Applications, 2019
We study rings in which [Formula: see text] nonzero idempotent implies [Formula: see text] is also an idempotent. We call such rings i-reversible. Besides studying the basic properties of i-reversible rings, we characterize i-reversible triangular matrix rings, i-reversible matrix rings over commutative rings and i-reversible exchange rings.
