Convexity in quasi-metric spaces [PDF]

open access: yes, 2012
Includes abstract.Includes bibliographical references.The principal aim of this thesis is to investigate the existence of an injective hull in the categories of T-quasi-metric spaces and of T-ultra-quasi-metric spaces with nonexpansive ...

Demiclosedness Principle for Total Asymptotically Nonexpansive Mappings in CAT(0) Spaces [PDF]

open access: yes, 2014
We prove the demiclosedness principle for a class of mappings which is a generalization of all the forms of nonexpansive, asymptotically nonexpansive, and nearly asymptotically nonexpansive mappings.

Structure of the fixed point set and common fixed points of asymptotically nonexpansive mappings [PDF]

open access: yes, 2001
Let X be a Banach space, C a weakly compact convex subset of X and T : C → C an asymptotically nonexpansive mapping. Under the usual assumptions on X which assure the existence of fixed point for T, we prove that the set of fixed points is a ...

An extragradient iterative scheme for common fixed point problems and variational inequality problems with applications

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2015
In this paper, by combining a modified extragradient scheme with the viscosity approximation technique, an iterative scheme is developed for computing the common element of the set of fixed points of a sequence of asymptotically nonexpansive mappings and

Triple Hierarchical Variational Inequalities, Systems of Variational Inequalities, and Fixed Point Problems

open access: yesMathematics, 2019
In this paper, we introduce a multiple hybrid implicit iteration method for finding a solution for a monotone variational inequality with a variational inequality constraint over the common solution set of a general system of variational inequalities ...

Demiclosed Principle for Asymptotically Nonexpansive Mappings in CAT(0) Spaces [PDF]

open access: yes, 2010
We prove the demiclosed principle for asymptotically nonexpansive mappings in CAT(0) spaces. As a consequence, we obtain a Δ-convergence theorem of the Krasnosel'skii-Mann iteration for asymptotically nonexpansive mappings in this setting. Our

A General Composite Algorithms for Solving General Equilibrium Problems and Fixed Point Problems in Hilbert Spaces

open access: yesAbstract and Applied Analysis, 2011
We introduce a general composite algorithm for finding a common element of the set of solutions of a general equilibrium problem and the common fixed point set of a finite family of asymptotically nonexpansive mappings in the ...

On Asymptotically Quasi-φ-Nonexpansive Mappings in the Intermediate Sense [PDF]

open access: yes, 2020
A projection iterative process is investigated for the class of asymptotically quasi-φ-nonexpansive mappings in the intermediate sense. Strong convergence theorems of common fixed points of a family of asymptotically quasi-φ-nonexpansive mappings in the ...
