Abstract

In this paper, we give a general inertial Krasnoselskii–Mann algorithm for solving inclusion problems in Banach Spaces. First, we establish a weak convergence in real uniformly convex and q-uniformly smooth Banach spaces for finding fixed points of nonexpansive mappings. Then, a strong convergence is obtained for the inertial generalized forward-backward splitting method for the inclusion. Our results extend many recent and related results obtained in real Hilbert spaces.

Summary

Introduction

Let X be a real Banach space and given a single and set-valued operators A : X → X and. The forward-backward splitting method (2) includes the proximal point algorithm, (see, e.g., [8,9,10,11,12]), and the gradient method (see, for example, [2,13]). Several other modifications of (2) with inertial extrapolation step have been considered in Hilbert spaces by many authors, see, for example, [17,18,19,20,21]. We extend the results of [17] concerning the inertial Krasnoselskii–Mann iteration for fixed point of nonexpansive mappings to uniformly convex and q-uniformly smooth Banach space. We extend the forward-backward splitting method with inertial extrapolation step for solving (1) from. While the mentioned results establish only weak convergence, we provide strong convergence analysis in Banach spaces.
