Abstract: A ring R is unit nil-clean if, for any $$a\in R$$a∈R, there exists a unit $$u\in R$$u∈R, such that ua is the sum of an idempotent and a nilpotent. In this paper, we completely describe… read more here.

Abstract: Abstract A ring is called strongly clean if each of its elements can be written as the sum of an idempotent and a unit which commute. In this paper, we deal with two questions: first,… read more here.

Abstract: Abstract A ring R is a strongly 2-nil-clean if every element in R is the sum of two idempotents and a nilpotent that commute. A ring R is feebly clean if every element in R… read more here.

Abstract: Abstract A ring is called nil clean if every element can be written as the sum of an idempotent and a nilpotent. The class of nil clean rings has emerged as an important variant of… read more here.

Abstract: A ring R is strongly weakly nil-clean if every element in R is the sum or difference of a nilpotent and an idempotent that commutes. We prove, in this paper, that a ring R is… read more here.

Abstract: Generalizing the notion of strongly nil clean rings, we introduce strongly quasi-nil clean rings. Some fundamental properties and equivalent characterizations of this class of rings are provided. By means of g-Drazin inverses, Cline’s formula and… read more here.
