带中央单元的环的稳定范围1

Stable range one for rings with central units

Paula A. A. B. Carvalho, Christian Lomp, Jerzy Matczuk

摘要:

本文的目的是部分肯定地回答Khurana等人提出的关于具有稳定值域1和中心单位的环$R$是否交换的问题。我们证明了在下列任何附加条件下都是这种情况:$R$是半素的或$R$是单侧诺特的或$R$有单位-稳定范围$1$或$R$具有经典克鲁尔维数$0$或$R$是域$K$上代数,使得$K$是不可数的且$R$仅具有可数多个本原理想或$R$是仿射的且$K$具有特征$0$或在其素子域上具有无限超越度或代数闭。然而,总的问题仍然悬而未决。

英文摘要:

The purpose of this paper is to give a partial positive answer to a question raised by Khurana et al. as to whether a ring $R$ with stable range one and central units is commutative. We show that this is the case under any of the following additional conditions: $R$ is semiprime or $R$ is one-sided Noetherian or $R$ has unit-stable range $1$ or $R$ has classical Krull dimension $0$ or $R$ is an algebra over a field $K$ such that $K$ is uncountable and $R$ has only countably many primitive ideals or $R$ is affine and either $K$ has characteristic $0$ or has infinite transcendental degree over its prime subfield or is algebraically closed. However, the general question remains open.
