We prove that Browder s and Halpern s type convergence theorems imply Moudafi s viscosity approximations with the weak contraction and give the estimate of convergence rate between Halpern s type iteration and Mouda s viscosity approximations with the weak contraction.

Introduction The following famous theorem is referred to as the Banach Contraction Principle. Theorem Banach 1 . Let fE d be a complete metric space and let A be a contraction on X that is there exists p e 0 1 such that d Ax Ay pd x yfi Nx y e E. Then A has a unique fixed point. In 2001 Rhoades 2 proved the following very interesting fixed point theorem which is one of generalizations of Theorem because the weakly contractions contains contractions as the special cases y fi 1 - p t . Theorem Rhoades 2 Theorem 2 . Let fE d be a complete metric space and let A be a weak contraction on E that is d Ax Ay d x y - y d x y Vx y e E 2 Fixed Point Theory and Applications for some p 0 x 0 x is a continuous and nondecreasing function such that p is positive on 0 x and p 0 0. Then A has a unique
