STRONGLY NIL CLEAN MATRICES OVER R[x]/(x2-1)
Chen, Huanyin;

Abstract
An element of a ring is called strongly nil clean provided that it can be written as the sum of an idempotent and a nilpotent element that commute. We characterize, in this article, the strongly nil cleanness of $\small{2{\times}2}$ and $\small{3{\times}3}$ matrices over $\small{R[x]/(x^2-1)}$ where $\small{R}$ is a commutative local ring with characteristic 2. Matrix decompositions over fields are derived as special cases.
