A note on the perturbation bounds of W-weighted Drazin inverse of linear operator in Banach space
Xuezhong Wang, Haifeng Ma, Marija Cvetković · Filomat · 2017
We investigate the perturbation bound of the W-weighted Drazin inverse for bounded linear operators between Banach spaces and present two explicit expressions for the W-weighted Drazin inverse of bounded linear operators in Banach space, which extend the results in Chin.
