초록

Let D be an integral domain, X be an indeterminate over D, and Nv = {f ∈ D[X]| (Af)v = D}. In this paper, we introduce the concept of t-locally divided domains, and we then prove that D[X]Nv is a locally divided domain if and only if D is a t-locally divided UMT-domain, if and only if D[X] is a t-locally divided domain.

Abstract

Let D be an integral domain, X be an indeterminate over D, and Nv = {f ∈ D[X]| (Af)v = D}. In this paper, we introduce the concept of t-locally divided domains, and we then prove that D[X]Nv is a locally divided domain if and only if D is a t-locally divided UMT-domain, if and only if D[X] is a t-locally divided domain.
