Abstract

Let K be a nonempty closed convex subset of a real Banach space E and T be a Lipschitz pseudocontractive self-map of K with F(T) := {x ε K : T x = x} ≠ Ø. An iterative sequence {xn} is constructed for which ∥xn - Txn∥ → 0 as n → ∞. If, in addition, AT is assumed to be bounded, this conclusion still holds without the requirement that F(T] ≠ Ø. Moreover, if, in addition, E has a uniformly Gâteaux differentiable norm and is such that every closed bounded convex subset of K has the fixed point property for nonexpansive self-mappings, then the sequence {xn} converges strongly to a fixed point of T, Our iteration method is of independent interest.
