چکیده

This paper deals with new methods for approximating a solution to the fixed point problem; find x̃ ∈ F T , where H is a Hilbert space, C is a closed convex subset of H, f is a ρ-contraction from C into H, 0 < ρ < 1, A is a strongly positive linear-bounded operator with coefficient γ > 0, 0 < γ < γ/ρ, T is a nonexpansive mapping on C, and PF T denotes the metric projection on the set of fixed point of T . Under a suitable different parameter, we obtain strong convergence theorems by using the projectionmethodwhich solves the variational inequality 〈 A−γf x̃ τ I−S x̃, x−x̃〉 ≥ 0 for x ∈ F T , where τ ∈ 0,∞ . Our results generalize and improve the corresponding results of Yao et al. 2010 and some authors. Furthermore, we give an example which supports our main theorem in the last part.

Strong convergence of variational inequality problem Over the set of common fixed points of a family of demi-contractive mappings

In this paper, by using the viscosity iterative method and the hybrid steepest-descent method, we present a new algorithm for solving the variational inequality problem. The sequence generated by this algorithm is strong convergence to a common element of the set of common zero points of a finite family of inverse strongly monotone operators and the set of common fixed points of a finite family...
