Abstract

Let X X be a real Banach space, let K K be a closed convex subset of X X , and let T T , from K K into X X , be a pseudo-contractive mapping (i.e. ( λ 1 ) (\lambda -1) u v ( λ I T ) ( u ) ( λ I T ) ( v ) \|u-v\|\le \|(\lambda I-T)(u)-(\lambda I-T)(v)\| for all u , v K u,v\in K and λ > 1 ) \lambda >1) . Suppose the space X X has a uniformly Gâteaux differentiable norm, such that every closed bounded convex subset of K K enjoys the Fixed Point Property for nonexpansive self-mappings. Then the path t x t K t\to x_t\in K , t [ 0 , 1 ) t\in [0,1) , defined by the equation x t = t T x t + ( 1 t ) x 0 x_t=tTx_t+(1-t)x_0 is continuous and strongly converges to a fixed point of T T as t 1 t\to 1^- , provided that T T satisfies the weakly inward condition.
