Abstract

Let RR be a ring, (S,)(S,\preceq) a strictly totally ordered monoid and suppose also ω:SEnd(R)\omega:S\rightarrow \text{End}(R) is a monoid homomorphism. A skew generalized power series ring R[[S,ω,]]R[[S,\omega,\preceq]] consists of all functions from a monoid SS to a coefficient ring RR whose support contains neither infinite descending chains nor infinite anti-chains, equipped with point-wise addition and with multiplication given by convolution twisted by an action ω\omega of the monoid SS on the ring RR. Special cases of the skew generalized power series ring construction are the skew polynomial rings, skew Laurent polynomial rings, skew power series rings, skew Laurent series rings, skew monoid rings, skew group rings, skew Malcev-Neumann series rings and generalized power series rings as well as the untwisted versions of all of these objects. In the present article, we study the so-termed (S,ω)(S,\omega)-McCoy condition on RR, that is a generalization of the standard McCoy condition from polynomials to skew generalized power series, thus generalizing some of the existing results in the literature relevant to the subject.
