Non-expansive mappings and iterative methods in uniformly convex Banach spaces. (English) Zbl 1083.47060

The author investigates the properties of iterative sequences for non-expansive mappings and presents several strong and weak convergence results of successive approximations to fixed points of non-expansive mappings in uniformly convex Banach spaces. The results presented in this article generalize and improve various ones concerned with constructive techniques for the fixed points of non-expansive mappings.
