| Abstract: | In this paper the notation of the Cline–Greville W-weighted Drazin inverse of a rectangular matrix is extended to bounded linear operators between Banach spaces. We give new characterizations of the W-weighted Drazin inverse, and we study the perturbations and the the continuity of the W-weighted Drazin inverse. |
| Keywords: | Weighted Drazin inverse Bounded operator Banach space Perturbation Continuity |
