Strongly Clean Matrices over Commutative Rings

H. Chen, H. Kose, Y. Kurtulmaz

A commutative ring $R$ is projective free provided that every finitely generated $R$ -module is free. An element in a ring is strongly clean provided that it is the sum of an idempo…

Uniquely Strongly Clean Triangular Matrix Rings

H. Chen, O. Gurgun, H. Kose

A ring $R$ is uniquely (strongly) clean provided that for any $a \in R$ there exists a unique idempotent $e \in R (\in co mm (a))$ such that $a - e \in U (R)$ . Let $R$ be a uniquel…

On Perfectly Clean Rings

H. Chen, S. Halicioglu, H. Kose

An element $a$ of a ring $R$ is called perfectly clean if there exists an idempotent $e \in co m m^{2} (a)$ such that $a - e \in U (R)$ . A ring $R$ is perfectly clean in case every element i…

Strongly clean triangular matrix rings with endomorphisms

H. Chen, H. Kose, Y. Kurtulmaz

A ring $R$ is strongly clean provided that every element in $R$ is the sum of an idempotent and a unit that commutate. Let $T_{n} (R, σ)$ be the skew triangular matrix ring over a loca…

The strong $P$ -cleanness over rings

Huanyin Chen, H. Kose, Y. Kurtulmaz

An element of a ring $R$ is strongly $P$ -clean provided that it can be written as the sum of an idempotent and a strongly nilpotent element that commute. A ring $R$ is strongly $P$ …
