The main purpose of this paper is to introduce an explicit iterative algorithm to study the existence problem and the approximation problem of solution to the quadratic minimization problem. Under suitable conditions some strong convergence theorems for a family of nonexpansive mappings are proved. The results presented in the paper improve and extend the corresponding results announced by some authors. 1. Introduction Throughout this paper we assume that H is a real Hilbert space with inner product and norm II II C is a nonempty closed convex subset of H and F T x e H Tx x is the set of fixed points of mapping T. A mapping S C C is called nonexpansive if Sx - Sy x - y Yx y e C. Let A H H be a single-valued nonlenear mapping and M H 2h be a multivalued mapping. The so-called quasivariational inclusion problem see 1-3 is to find u e H such that e e A u M u . The set of solutions to quasivariational inclusion problem is denoted by VI H A M . 2 Fixed Point Theory and Applications Special Cases I If M dộ H 2H where ộ H R J i is a proper convex lower semi-continuous function and dộ is the subdifferential of ộ then the quasivariational inclusion problem is equivalent to finding u e H such that A u y - u ộ y -
