| Abstract: | Let $R$ be a ring. We show in the paper that the subring $U_n(R)$ of the upper triangular matrix ring $T_n(R)$ is $\overline{\alpha}$-skew Armendariz if and only if $R$ is $\alpha$-rigid, also it is maximal in some non $\overline{\alpha}$-skew Armendariz rings, where $\alpha$ is a ring endomorphism of $R$ with $\alpha(1)=1$. |
