| Abstract: | In this paper,we have carried on the preliminary inquisition to perturbation analysis for Moore-Penrose metric generalized inverse of bounded linear operators in Banach space.In here,we have given the definition of stable perturbation,and then we apply this definition and generalized orthogonal decomposition theorem to give under certain norm Moore-Penrose metric generalized inverse error bound estimate. |
