Abstract:In this paper we establish a dual weak convergence theorem for the Ishikawa iteration process for nonexpansive mappings in a reflexive and strictly convex Banach space with a uniformly Gâteaux differentiable norm, and then apply this result to study the problem of the weak convergence of the iteration process.
Keywords:Banach limit  dual convergence theorem  duality mapping  Ishikawa iteration process  nonexpansive mapping
