A note on the perturbation bounds of W-weighted Drazin inverse
Xuezhong Wang, Haifeng Ma, Jovana Nikolov Radenković · Linear and Multilinear Algebra · 2016
We investigate the perturbation bound for the W-weighted Drazin inverse of a rectangular matrix and present two explicit expressions for the W-weighted Drazin inverse under the one-sided condition, which extends the results in Appl. Math. Comput. 2004;149:423–430.
