We introduce a new iterative algorithm for a system of generalized equilibrium problems and a countable family of strict pseudocontractions in Hilbert spaces. We then prove that the sequence generated by the proposed algorithm converges strongly to a common element in the solutions set of a system of generalized equilibrium problems and the common fixed points set of an infinitely countable family of strict pseudocontractions. 1. Introduction Let H be a real Hilbert space with the inner product and inducted norm II . Let C be a nonempty closed and convex subset of H. Let fk keA C X C X be a family of bifunctions and let Ak keA C H be a family of nonlinear mappings where A is an arbitrary index set. The system of generalized equilibrium problems is to find x e C such that fk x y Akx y - x 0 Vy e C k e A. If A is a singleton then reduces to find x e C such that f x y Ax y - x 0 Vy e C. The solutions set of is denoted by GEP f A . If f 0 then the solutions set of is denoted by VI C A and if A 0 then the solutions set of is denoted by EP f . 2 Fixed Point .
