چکیده
|
let $r$ be a $ 2$-torsion-free semiprime ring and $theta$ be an epimorphism of $r$. in this paper, under special hypotheses, we prove that if $t: rlongrightarrow r$ is an additive mapping such that$$t(xyx)=θ(x)t(y)θ(x),$$holds for all $x, yin r$, then $t$ is a $θ$-centralizereither $r$ is unital or $θ(z(r))=z(r)$.
