Convergence of Multi-step Iterates with Errors for Uniformly Quasi-Lipschitzian Mappings

The aim of this paper is to give some necessary and sufficient conditions for multi-step iterative scheme with errors for a nite family of uniformly quasi-Lipschitzian mappings to converge to common fixed point in a real Banach space. Our results extend and improve the corresponding results of Quan [7], Liu [5, 6], Xu and Noor [9] and many others.
