Ore Extensions of Extended Symmetric and Reversible Rings

Abstract

Let $σ$ be an endomorphism and $δ$ an $σ$-derivation of a ring $R$. In this paper, we show that if $R$ is $(σ,δ)$-skew Armendariz and $aσ(b)=0$ implies $ab=0$ for $a,b\in R$. Then $R$ is symmetric (respectively, reversible) if and only if $R$ is $σ$-symmetric (respectively, $σ$-reversible) if and only if $R[x;σ,δ]$ is symmetric (respectively, reversible). Moreover, we study on the relationship between the Baerness, quasi-Baerness and p.q.-Baerness of a ring $R$ and these of the Ore extension $R[x;σ,δ]$. As a consequence we obtain a partial generalization of \cite{hong/2000}.
