Rings involving idempotents, units and nilpotent elements

Nahid Ashrafi, Marjan Sheibani, Huanyin Chen

We define the concepts of weakly precious and precious rings which generalize the notions of weakly clean and nil-clean rings. We obtain some fundamental properties of these rings.…

Extensions of square stable range one

Huanyin Chen, Marjan Sheibani

An ideal $I$ of a ring $R$ is square stable if $a R + b R = R$ with $a \in I$ and $b \in R$ implies that $a^{2} + b y$ is invertible in $I$ for some $y \in I$ . We prove that an exchange ideal $I…

Uniquely weakly nil-clean conditions on zero-divisors

H. Chen, M. Sheibani

An element in a ring $R$ is called uniquely weakly nil-clean if every element in $R$ can be uniquely written as a sum or a difference of a nilpotent and an idempotent in the sense…
