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…

Dual $π$ -Rickart Modules

Burcu Ungor, Yosum Kurtulmaz, Sait Halıcıoglu +1

Let $R$ be an arbitrary ring with identity and $M$ a right $R$ -module with $S =$ End $_{R} (M)$ . In this paper we introduce dual $π$ -Rickart modules as a generalization of $π$ -regular…
