We introduce a new iterative scheme for finding a common element of the set of solutions of the equilibrium problems the set of solutions of variational inequality for a relaxed cocoercive mapping and the set of fixed points of a nonexpansive mapping. The results presented in this paper extend and improve some recent results of Ceng and Yao 2008 Yao 2007 S. Takahashi and W. Takahashi 2007 Marino and Xu 2006 Iiduka and Takahashi 2005 Su et al. 2008 and many others. 1. Introduction Throughout this paper we always assume that H is a real Hilbert space with inner product and norm II II respectively C is a nonempty closed and convex subset of H and Pc is the metric projection of H onto c. In the following we denote by strong convergence by weak convergence and by R the real number set. Recall that a mapping S c c is called nonexpansive if Sx - Syll x - y Nx y e c. We denote by F S the set of fixed points of the mapping S. For a given nonlinear operator A consider the problem of finding u e c such that Au v - u 0 Vv e c 2 Journal of Inequalities and Applications which is called the variational inequality. For the recent applications sensitivity analysis dynamical
