局部稳定环上的初等矩阵约化

Elementary matrix reduction over locally stable rings

Marjan Sheibani Abdolyousefi, Rahman Bahmani Sangesari, Huanyin Chen

摘要:

交换环R是局部稳定的,如果对任意$a,b\in R$,使得$aR+bR=R$,存在$y\in R$,使得$R/(a+by)R$有稳定值域1.对于Bezout环$R$,我们证明了$R$是初等因子环当且仅当$R$是局部稳定的当且仅当$R$有纯值域1.

英文摘要:

A commutative ring R is locally stable provided that for any $a,b\in R$ such that $aR+bR=R$, there exist some $y\in R$ such that $R/(a+by)R$ has stable range 1.For a Bezout ring $R$, we prove that $R$ is an elementary divisor ring if and only if $R$ is locally stable if and only if $R$ has neat range 1.
