Kirk We introduce an iterative method for finding a common element of the set of common fixed points of a countable family of nonexpansive mappings the set of solutions of a variational inclusion with set-valued maximal monotone mapping and inverse strongly monotone mappings and the set of solutions of an equilibrium problem in Hilbert spaces. Under suitable conditions some strong convergence theorems for approximating this common elements are proved. The results presented in the paper improve and extend the main results of J. W. Peng et al. 2008 and many others. Copyright 2009 S. Plubtieng and W. Sriprad.

Introduction Let H be a real Hilbert space whose inner product and norm are denoted by and II II respectively. Let C be a nonempty closed convex subset of H and let F be a bifunction of C X C into R where R is the set of real numbers. The equilibrium problem for F C X C R is to find x e C such that F x y 0 Vy e C. The set of solutions of is denoted by EP F . Recently Combettes and Hirstoaga 1 introduced an iterative scheme of finding the best approximation to the .
