Approximating Fixed Points of Nonexpansive Mappings

We consider a mapping S of the form S =α0I+α1T1+α2T2+···+αkTk, where αi ≥ 0, α0 > 0, α1 > 0 and ∑k i=0αi = 1. We show that the Picard iterates of S converge to a common fixed point of Ti (i = 1,2, . . . ,k) in a Banach space when Ti (i = 1,2, . . . ,k) are nonexpansive.

Approximating Fixed Points of Nonexpansive Mappings

Let D be a subset of a normed space X and T : D → X be a nonexpansive mapping. In this paper we consider the following iteration method which generalizes Ishikawa iteration process: xn+1 = t (1) n T (t (2) n T (· · ·T (t (k) n Txn + (1− t (k) n )xn + u (k) n ) + · · · ) +(1− t n )xn + u (2) n ) + (1− t (1) n )xn + u (1) n , n = 1, 2, 3 . . . , where 0 ≤ t (i) n ≤ 1 for all n ≥ 1 and i = 1, . . ...

Approximating fixed points for nonexpansive mappings and generalized mixed equilibrium problems in Banach spaces

We introduce a new iterative scheme for nding a common elementof the solutions set of a generalized mixed equilibrium problem and the xedpoints set of an innitely countable family of nonexpansive mappings in a Banachspace setting. Strong convergence theorems of the proposed iterative scheme arealso established by the generalized projection method. Our results generalize thecorresponding results...

Convergence of approximating fixed points sets for multivalued nonexpansive mappings

Let K be a closed convex subset of a Hilbert space H and T : K ⊸ K a nonexpansive multivalued map with a unique fixed point z such that {z} = T (z). It is shown that we can construct a sequence of approximating fixed points sets converging in the sense of Mosco to z.

Approximating Fixed Points of Nonexpansive Mappings in Hyperspaces

Let X be a nonempty compact subset of a Banach space (E,‖·‖), and let C(X) and CC(X) denote the families of all nonempty compact and all nonempty compact convex subsets of X , respectively. It is well known that (C(X),H) is compact, where H is the Hausdorff metric induced by ‖·‖. For A,B ∈ CC(X) and t ∈ R = (−∞,+∞), let A + B = {a + b : a∈ A, b ∈ B}, and let tA= {ta : a∈ A}. In the sequel, we a...
