We introduce a new iterative scheme with Meir-Keeler contractions for strict pseudocontractions in -uniformly smooth Banach spaces. We also discuss the strong convergence theorems for the new iterative scheme in q-uniformly smooth Banach space. Our results improve and extend the corresponding results announced by many others. 1. Introduction Throughout this paper we denote by E and E a real Banach space and the dual space of E respectively. Let C be a subset of E and lrt T be a non-self-mapping of C. We use F T to denote the set of fixed points of T. The norm of a Banach space E is said to be Gateaux differentiable if the limit x y - Hx lim------Z-T------ tF 0 t exists for all x y on the unit sphere S E x e E x 1 . If for each y e S E the limit is uniformly attained for x e S E then the norm of E is said to be uniformly Gateaux differentiable. The norm of E is said to be Frechet differentiable if for each x e S E the limit is attained uniformly for y e S E . The norm of E is said to be uniformly Frechet differentiable or uniformly smooth if the limit is attained uniformly for x y e S E X S E . 2 Fixed Point
