Abstract

In this paper, we reconsider the iterative method X-k = Xk-1 + beta Y (I - AX(k-1)), k = 1, 2, ..., beta is an element of C \ 0 for computing the generalized inverse A(T,S)((2)) Banach spaces or the generalized Drazin inverse a(d) of a Banach algebra element a, reveal the intrinsic relationship between the convergence of such iterations and the existence of A(T,S)((2)) or a(d), and present the error bounds of the iterative methods for approximating A(T,S)((2)) or a(d). Moreover, we deduce some necessary and sufficient conditions for iterative convergence to A(T,S)((2)) or a(d).
