Generalized symmetric rings
In this paper, we introduce a class of rings which is a generalization of symmetric rings. Let \(R\) be a ring with identity. A ring \(R\) is called central symmetric if for any \(a\), \(b, c\in R\), \(abc = 0\) implies bac belongs to the center of \(R\). Since every symmetric ring is central sy...

Algebra and Discrete Mathematics| Резюме: | In this paper, we introduce a class of rings which is a generalization of symmetric rings. Let \(R\) be a ring with identity. A ring \(R\) is called central symmetric if for any \(a\), \(b, c\in R\), \(abc = 0\) implies bac belongs to the center of \(R\). Since every symmetric ring is central symmetric, we study sufficient conditions for central symmetric rings to be symmetric. We prove that some results of symmetric rings can be extended to central symmetric rings for this general settings. We show that every central reduced ring is central symmetric, every central symmetric ring is central reversible, central semmicommutative, 2-primal, abelian and so directly finite. It is proven that the polynomial ring \(R[x]\) is central symmetric if and only if the Laurent polynomial ring \(R[x, x^{-1}]\) is central symmetric. Among others, it is shown that for a right principally projective ring \(R\), \(R\) is central symmetric if and only if \(R[x]/(x^n)\) is central Armendariz, where \(n\geq 2~\) is a natural number and \((x^n)\) is the ideal generated by \(x^n\). |
