STRONGLY CLEAN ELEMENTS IN A CERTAIN BLOCK MATRIX RING

Abolfazl Nikkhah, Bijan Davvaz

Abstract


In this paper, we investigate the concepts of strongly clean, strongly $\pi$-regular and strongly $J_n$-clean related to the ring $A=\begin{pmatrix}
R&_RM_S\\0&S
\end{pmatrix}$. Moreover, we give several equivalent conditions such that an element $\alpha\in End(A)$  is strongly clean.
