Viscosity Approximation Methods for Nonexpansive Nonself-Mappings in Hilbert Spaces
Viscosity approximation methods for nonexpansive nonself-mappings are studied. Let C be a nonempty closed convex subset of Hilbert space H , P a metric projection of H onto C and let T be a nonexpansive nonself-mapping from C into H . For a contraction f on C and {tn} ⊆ (0,1), let xn be the unique fixed point of the contraction x → tn f (x) + (1− tn)(1/n) ∑n j=1(PT) x. Consider also the iterati...
متن کاملApproximation of fixed points for a continuous representation of nonexpansive mappings in Hilbert spaces
This paper introduces an implicit scheme for a continuous representation of nonexpansive mappings on a closed convex subset of a Hilbert space with respect to a sequence of invariant means defined on an appropriate space of bounded, continuous real valued functions of the semigroup. The main result is to prove the strong convergence of the proposed implicit scheme to the unique solutio...
متن کاملViscosity approximation methods for nonexpansive mappings in CAT(0) spaces
The purpose of this paper is to study the strong convergence theorems of Moudafi's viscosity approximation methods for a nonexpansive mapping T in CAT(0) spaces without the property P. For a contraction f on C and t ∈ (0, 1), let x t ∈ C be the unique fixed point of the contraction x → tf (x) ⊕ (1 – t)Tx; i.e., x t = tf (x t) ⊕ (1 – t)Tx t and x n+1 = α n f (x n) ⊕ (1 – α n)Tx n , n ≥ 0, where ...
متن کاملViscosity approximation methods for W-mappings in Hilbert space
We suggest a explicit viscosity iterative algorithm for nding a common elementof the set of common xed points for W-mappings which solves somevariational inequality. Also, we prove a strong convergence theorem with somecontrol conditions. Finally, we apply our results to solve the equilibrium problems.Finally, examples and numerical results are also given.
متن کاملOn the Strong Convergence of Viscosity Approximation Process for Quasinonexpansive Mappings in Hilbert Spaces
and Applied Analysis 3 But this fails; for example, let us consider the nonexpansive mapping T : R → R defined by Tx −x for all x ∈ R. It is clear that Fix T {0} and 〈x − Tx, x − q〉 2x2 /≥ 4x2 ‖x − Tx‖2. Recall the following identities in a Hilbert space H: for x, y ∈ H, ω ∈ 0, 1 i ‖x y‖2 ‖x‖2 2〈x, y〉 ‖y‖2; ii ‖ 1 −ω x ωy‖2 1 −ω ‖x‖2 ω‖y‖2 − 1 −ω ω‖x − y‖2. The correction of Maingé’s result is ...
