论文摘要
我们为圈中的组可逆性提出了新的添加结果。然后,我们将结果应用于在Banach空间上阻止操作员矩阵,并得出$ 2 \ times 2 $块操作员矩阵的组倒置的存在。这些概括了许多已知结果,例如Benitez,Liu和Zhu(线性多线性代数,{\ BF 59}(2011),279--289)和Zhou,Chen和chu(Comm。Elgebra,eLgebra,{\ Bf 48}(2020)(2020),676-676-690)。
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).
