In Banach spaces, we study the problem of solving a more general variational inequality system for an asymptotically non-expansive mapping. We give a new viscosity approximation scheme to find a common element. Some strong convergence theorems of the proposed iterative method are obtained. A numerical experiment is given to show the implementation and efficiency of our main theorem. Our results presented in this paper generalize and complement many recent ones.

IntroductionThroughout this paper, let X be a real Banach space and E ⊂ X be a nonempty subset. Let T : E → E be a mapping, the set of fixed points of T is denoted by F(T). If there exists a sequence {k n } ⊂ [1, ∞) with lim n→∞ k n = 1 such thatthen T is said to be asymptotically nonexpansive. T is uniformly asymptotically regular, if lim n→∞ T n+1 ξ − T n ξ = 0, ∀ξ ∈ E. If k n ≡ 1, then T is said to be nonexpansive. Recall that T is known as a contractive mapping on E if there exists a constant ρ ∈ (0, 1) such thatwhere J : X → 2 X * is the normalized duality mapping on X. An operator A : E → X is called α-inverse strongly accretive if for α > 0 and j(ξ − η) ∈ J(ξ − η), we haveFor any ∈ (0, 2], we denote the the modulus of convexity δ X ( ) > 0 of X as follows:
