Introduction and preliminaries Let H be a real Hilbert space with norm - and inner product C a nonempty closed convex subset of H and A a monotone operator of C into H. The classical variational inequality problem is formulated as finding a point x e C such that y - x Ax 0 for all y e C. Such a point x e C is called a solution of the variational inequality . Next the set of solutions of the variational inequality is denoted by VI C A . In the case when C H VI H A A-10 holds where A-10 x e H Ax 0 . Recall that an operator A of C into H is said to be inverse strongly monotone if there exists a positive real number a such that x - y Ax - Ay aỊỊAx - Ay 2 for all x y e C see 1-4 . For such a case A is said to be a-inverse strongly monotone. 2 Journal of Inequalities and Applications Recall that T C C is nonexpansive if Tx - Tyll x - y for all x y C. It is known that if T is a nonexpansive mapping of C into itself then A I-T is 1 2-inverse strongly monotone and F T VI C A where F T denotes the set of fixed points of T. Let PC be the .
