| contents | Let $R$ be a ring, $e$ an idempotent of $R$ and $δ(R)$ denote the intersection of all essential maximal right ideals of $R$ which is called Zhou radical. In this paper, the Zhou radical of a ring is applied to the $e$-reduced property of rings. We call the ring $R$ {\it Zhou right} (resp. {\it left}) {\it $e$-reduced} if for any nilpotent $a$ in $R$, we have $ae\in δ(R)$ (resp. $ea\in δ(R))$. Obviously, every ring is Zhou $0$-reduced and a ring $R$ is Zhou right (resp., left) $1$-reduced if and only if $N(R)\subseteq δ(R)$. So we assume that the idempotent $e$ is nonzero. We investigate basic properties of Zhou right $e$-reduced rings. Furthermore, we supply some sources of examples for Zhou right $e$-reduced rings. In this direction, we show that right $e$-semicommutative rings (and so right $e$-reduced rings and $e$-symmetric rings), central semicommutative rings and weak symmetric rings are Zhou right $e$-reduced. As an application, we deal with some extensions of Zhou right $e$-reduced rings. Full matrix rings need not be Zhou right $e$-reduced, but we present some Zhou right $e$-reduced subrings of full matrix rings over Zhou right $e$-reduced rings. |
