A Note on the Perturbation Bounds of W-weighted Drazin Inverse of Linear Operator in Banach Space

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 inChin.
