On the Convergence of Some Iteration Processes in Uniformly Convex Banach Spaces
J. Gwinner · Proceedings of the American Mathematical Society · 1978
For the approximation of fixed points of a nonexpansive operator T in a uniformly convex Banach space E the convergence of the Mann-Toeplitz iteration ${x_{n + 1}} = {\alpha _n}T({x_n}) + (1 - {\alpha _n}){x_n}$ is studied. Strong convergence is established for a special class of operators T. Via regularization this result can be used for general nonexpansive operators, if E possesses a weakly sequentially continuous duality mapping. Furthermore strongly convergent combined regularization-iteration methods are presented.
