Abstract

Let D be an integral domain and w be the so-called w-operation on D. In this note, we introduce the notion of (w)-domains: D is a (w)-domain if (((xi))((yj)))w=(xiyj) for all nonzero elements x1,,xm;y1,,yn of D. We then show that D is a Pr\"ufer v-multiplication domain if and only if D is a (w)-domain and A1 is of finite type for all nonzero finitely generated fractional ideals A of D.
