THREE-STEP ITERATION PROCESS FOR A FINITE FAMILY OF ASYMPTOTICALLY QUASI-NONEXPANSIVE MAPPINGS IN THE INTERMEDIATE SENSE IN CONVEX METRIC SPACES

The purpose of this paper is to establish some strong convergence theorems of three-step iteration process with errors for approximating common fi xed points for a fi nite family of asymptotically quasi-nonexpansive mappings in the intermediate sense in the setting of convex metric spaces. The results obtained in this paper generalize, improve and unify some main results of [1]-[7], [9]-[11], [13]-[17], [19] and [21].
