In this article, we deal with generalizations of Wittmann's strong convergencetheorem for nonexpansive mappings and then study strong convergence theoremsfor a finite family of nonexpansive mappings in a Banach space. Further, we deal withconvergence theorems which are connected with the problem of image recovery. Finally,we consider the problem of finding a common fixed point for a finite commuting familyof nonexpansive mappings in a Banach space.Convex Analysis and Chaos : The Third Symposium on Nonlinear Analysis, July 23-25, 1998 Josai University, edited by Kiyoko Nishizawa
