摘要: R为正则环, A∈ Mn(R). 如果Mn(R)AMn(R)为Mn(R) 的内射理想,该文证明了有U, V∈ GLn(R)使得UAV为对角矩阵.

关键词: 内射理想, 可分理想, 正则环.

Abstract: Let R be regular, A∈ Mn(R). If Mn(R)AMn(R) is injective as a right Mn(R)-module,
we prove that there exist U, V∈ GLn(R) such that UAV is a diaogonal matrix.

Key words: Injective ideal, Separative ideal, Regular ring.
