Abstract

In this paper, we study stationary and nonstationary methods to approximate fixed points of a general class of nonexpansive type mappings in Banach spaces under certain conditions. We obtain weak convergence of a sequence of iterates of nonexpansive type mappings. We also present a stability result for nonstationary methods. We obtain data dependency analysis of the nonstationary methods. Moreover, we present a numerical example to demonstrate the convergence behaviour of the nonstationary methods. Finally, we pose an open problem.
