New Perturbation Theorem on Drazin Inverse of Linear Operator in Banach Spaces
Ying Liu · Shuxue de shijian yu renshi · 2011
In this paper,we discuss the perturbation problem on Drazin inverse of bounded linear operator in Banach spaces.By the generalized Neumann Lemma given by Jiu Ding in 2003,new perturbation theorem and error estimate is given in this paper,which extend the perturbation results in literature.
