Abstract

Let RR be a ring with identity, (S,)(S,\leq) an ordered monoid, ω:SEnd(R)\omega:S \to End(R) a monoid homomorphism, and A=R[[S,ω]]A= R\left[\left[S,\omega \right]\right] the ring of skew generalized power series. The concepts of generalized Baer and generalized quasi-Baer rings are generalization of Baer and quasi-Baer rings, respectively. A ring RR is called generalized right Baer (generalized right quasi-Baer) if for any non-empty subset SS (right ideal II) of RR, the right annihilator of Sn 0.1cm(In)S^n \space{0.1cm}(I^n) is generated by an idempotent for some positive integer nn. Left cases may be defined analogously. A ring RR is called generalized Baer (generalized quasi-Baer) if it is both generalized right and left Baer (generalized right and left quasi-Baer) ring. In this paper, we examine the behavior of a skew generalized power series ring over a generalized right Baer (generalized right quasi-Baer) ring and prove that, under specific conditions, the ring AA is generalized right Baer (generalized right quasi-Baer) if and only if RR is a generalized right Baer (generalized right quasi-Baer) ring.
