Abstract

Let RR be a commutative ring with 101\neq 0 and nn be a fixed positive integer. A proper ideal II of RR is said to be an \textit{nn-OA ideal} if whenever a1a2an+1Ia_1a_2\cdots a_{n+1}\in I for some nonunits a1,a2,,an+1Ra_1,a_2,\ldots,a_{n+1}\in R, then a1a2anIa_1a_2\cdots a_n\in I or an+1Ia_{n+1}\in I. A commutative ring RR is said to be an \textit{nn-OAF ring} if every proper ideal II of RR is a product of finitely many nn-OA ideals. In fact, 11-OAF rings and 22-OAF 22-OAF-rings are exactly the general ZPI rings and OAF rings, respectively. In addition to giving various properties of nn-OAF rings, we give a characterization of Noetherian von Neumann regular rings in terms of our new concept. Furthermore, we investigate the nn-OAF property of some extension of rings such as the polynomial ring R[X]R[X], the formal power series ring R[[X]]R[[X]], the ring of A+XB[X]A+XB[X], and the trivial extension R=AER=A\propto E of an AA-module EE.
