The viscosity approximation methods are employed to establish strong convergence theorems of the modified Mann iteration scheme to A-strict pseudocontractions in p-uniformly convex Banach spaces with a uniformly Gateaux differentiable norm. The main result improves and extends many nice results existing in the current literature. 1. Introduction Let E be a real Banach space and let C be a nonempty closed convex subset E. We denote by J the normalized duality map from E to 2E defined by Jx A p E x 2 X 2 p e1. J x x 3 x x x x x 3 . . A mapping T C C is said to be a l-strictly pseudocontractive mapping see . 1 if there exists a constant 0 A 1 such that Tx - TyW2 IIx - y II2 All I - T x - I - T y 2 2 Fixed Point Theory and Applications for all x y e C. We note that the class of T-strict pseudocontractions strictly includes the class of nonexpansive mappings which are mapping T on C such that Tx - Ty x - yịị for all x y e C. Obviously T is nonexpansive if and only if T is a 0-strict pseudocontraction. A mapping T C C is said to be a T-strictly pseudocontractive mapping with respect to p if for all x y e C there
