环中和的群可逆性及其应用

Group invertibility of the sum in rings and its applications

Huanyin Chen, Dayong Liu, Marjan Sheibani

摘要:

给出了环中群可逆性的新的加法结果。然后将所得结果应用于巴拿赫空间上的块算子矩阵,得到了$2\times 2$块算子矩阵群逆的存在性.这些推广了许多已知的结果,例如,Benitez,Liu和Zhu(Linear多重线性代数,{ \bf 59}(2011),279- 289)以及Zhou,Chen和Zhu(Comm. Algebra,{ \bf 48}(2020),676 -690)。

英文摘要:

We present new additive results for the group invertibility in a ring. Then we apply our results to block operator matrices over Banach spaces and derive the existence of group inverses of $2\times 2$ block operator matrices. These generalize many known results, e.g., Benitez, Liu and Zhu(Linear Multilinear Algebra, {\bf 59}(2011), 279--289) and Zhou, Chen and Zhu(Comm. Algebra, {\bf 48}(2020),676-690).
