Bézout域上矩阵的群可逆性

The group invertibility of matrices over Bézout domains

Dayong Liu, Aixiang Fang

摘要:

设$R$是Bézout整环,并设$A,B,C\in R^{n\times n}$具有$ABA=ACA$ .如果$AB$和$CA$是群可逆的,我们证明了$AB$和$CA$是相似的.此外,我们有$(AB)^{\#}$类似于$(CA)^{\#}$。这推广了Cao和Li(Group inverses for matrices over a Bézout domain,{ \it Electronic J.线性代数},{ \bf 18}(2009),600- 612)的主要结果。

英文摘要:

Let $R$ be a Bézout domain, and let $A,B,C\in R^{n\times n}$ with $ABA=ACA$. If $AB$ and $CA$ are group invertible, we prove that $AB$ is similar to $CA$. Moreover, we have $(AB)^{\#}$ is similar to $(CA)^{\#}$. This generalize the main result of Cao and Li(Group inverses for matrices over a Bézout domain, {\it Electronic J. Linear Algebra}, {\bf 18}(2009), 600--612).
