CONVERGENCE THEOREMS OF THE ITERATIVE SCHEMES IN CONVEX METRIC SPACES

Abstract

The purpose of this paper is to study the convergence problem of Mann and Ishikawa type iterative schemes of weakly contractive mapping in a complete convex metric space. We establish the results on invariant approximation for the mapping defined on a class of nonconvex sets in a convex metric space. Finally, we obtain the existence of common fixed points of two asymptotically nonexpansive mappings through the convergence of iteratively defined sequence in a uniformly convex metric space.
