Keywords Generalized mixed equilibrium problem Asymptotically quasi- j -nonex-pansive mapping Strong convergence theorem Variational inequality Banach spaces 1. Introduction Let E be a Banach space with norm - C be a nonempty closed convex subset of E and let E denote the dual of E. Let f CxC R be a bifunction Ộ C R be a real-valued function and B C E be a mapping. The generalized mixed equilibrium problem is to find x e C such that f x y Bx y x p y p x 0 Vy e C. 1.1 The set of solutions to 1.1 is denoted by GMEPf B Q i.e. GMEP f B p x e C f x y Bx y x p y p x 0 Vy e C . 1.2 If B 0 then the problem 1.1 reduces into
