在Banach代数元素a和b上的新条件下,我们得到了和的广义Drazin逆的显式表达式。作为结果的应用,我们给出了Banach代数中分块矩阵的广义Drazin逆的新表示。
Under new conditions on Banach algebra elementsaandb, we derive explicit expressions for the generalized Drazin inverse of the sum. As an application of our results, we present new representations for the generalized Drazin inverse of a block matrix in a Banach algebra.
