UNIT-REGULARITY AND STABLE RANGE ONE Chen, Huanyin;
Abstract
Let R be a ring, and let (R) be the ideal generated by the set {x R | 1 + sxt R is unit-regular for all s, t R}. We show that (R) has "radical-like" property. It is proven that (R) has stable range one. Thus, diagonal reduction of matrices over such ideal is reduced.
