摘要
研究了Banach空间中算子的广义Drazin逆,得到了广义Drazin逆的一些刻画,并对具有相同谱投影算子的扰动界进行了估计。
The generalized Drazin inverse of Banach space operators was studied. Some characterizations of the generalized Drazin inverse were obtained, and the perturbation bound of operators with equal spectral projection related to their generalized Drazin inverse was estimated.
