Abstract

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