S-可除模及S-Dedekind环
S-divisible Modules and S-Dedekind Rings
摘要
Abstract
Let R be a ring and M be a R-module.Let S denote the regular multiplicative closed set of the center in R.If Ext(R/Ru,M)=0,for any regular element u∈S,then M is called an S-divisible modules.A left R-module E is called an S-regular injective if Ext(R/I,E)=0 for any S-regular left ideal I.R is called an S-Notherian rings if every S-regular left ideal in R is finitely generated.A commutative ring is called an S-Dedekind ring if every S-regular ideal in R is invertible.In this paper,we discuss the basic properties of S-Noetherian rings.With S-divisible modules characterized S-Dedekind rings,it is also shown that R is an S-Dedekind rings if and only if S-divisible modules are S-regular injective modules.关键词
