Fixed points of nonexpansive and quasi-nonexpansive mappings

The Journal of Analysis, 2018
As answers to open questions raised by \textit{V. Colao} and \textit{G. Marino} [Fixed Point Theory Appl. 2015, Paper No. 39, 7 p. (2015; Zbl 1307.47077)], the authors show strong and weak convergence of the iterated sequence by the Krasnoselskii-Mann algorithm for a countable family of (quasi-)nonexpansive non-self mappings satisfying a weakly inward ...

Asymptotically nonexpansive mappings

Nonlinear Analysis: Theory, Methods & Applications, 1998
This is a very interesting paper. The method used suggests an entirely new approach in the study of fixed points and related properties of asymptotically nonexpansive mappings. Let \(E\) be a Banach space and \(D\subseteq E\). We recall, if there exists a sequence of reals \(\{k_i\}\) with \(k_i\downarrow 1\) such that \(\|T^ix- T^iy\|\leq k_i\|x-y\|\)

On the Convergence of the Products of Firmly Nonexpansive Mappings

SIAM Journal on Optimization, 1992
Consider a finite collection of firmly nonexpansive self-mappings on a Hilbert space whose fixed-point sets intersect. It is shown that, in the finite-dimensional case, any iteration of mappings drawn from this collection converges. This resolves, for the finite-dimensional case at least, a popular conjecture concerning the convergence of the ...

Successive Averages of Firmly Nonexpansive Mappings

Mathematics of Operations Research, 1995
The problem considered here is to find common fixed points of (possibly infinitely) many firmly nonexpansive selfmappings in a Hilbert space. For this purpose we use averaged relaxations of the original mappings, the averages being Bochner integrals with respect to chosen measures.

CONVERGENCE OF ITERATIVE SCHEMES FOR NONEXPANSIVE MAPPINGS

Asian-European Journal of Mathematics, 2011
Let K be a nonempty closed convex subset of a real uniformly convex Banach space X and suppose T : K → K is a nonexpansive mapping with the nonempty fixed point set Fix(T). Let [Formula: see text], [Formula: see text] and [Formula: see text] be sequences in [0, 1] such that [Formula: see text][Formula: see text][Formula: see text] for some constants a,

Strong convergence theorems for nonexpansive mappings and nonexpansive semigroups

1997
Summary: Let \(C\) be a closed, convex subset of a Banach space, let \(T\) be a nonexpansive mapping from \(C\) into itself such that the set \(F(T)\) of fixed points of \(T\) is nonempty and let \(\{T(t): t\geq 0\}\) be a nonexpansive semigroup on \(C\) such that the set \(\cap_{t\geq 0}F (T(t))\) of common fixed points of \(\{T(t): t\geq 0\}\) is ...
