Strongly Rad-clean Matrices over Commutative Local Rings

Huanyin Chen, Handan Kose, Yosum Kurtulmaz

An element $a \in R$ is provided that there exists an idempotent $e \in R$ such that $a - e \in U (R), a e = e a$ and $e a e \in J (e R e)$ . In this article, we investigate strongly rad-clean matr…

Factorizations of Matrices Over Projective-free Rings

H. Chen, H. Kose, Y. Kurtulmaz

An element of a ring $R$ is called strongly $J^{#}$ -clean provided that it can be written as the sum of an idempotent and an element in $J^{#} (R)$ that commute. We characterize,…

On feckly clean rings

H. Chen, H. Kose, Y. Kurtulmaz

A ring $R$ is feckly clean provided that for any $a \in R$ there exists an element $e \in R$ and a full element $u \in R$ such that $a = e + u, e R (1 - e) \subseteq J (R)$ . We prove that a rin…
