Common fixed points versus invariant approximation for noncommutative mappings [PDF]

open access: yesJournal of Numerical Analysis and Approximation Theory, 2008
The aim of this paper is to obtain common fixed points as invariant approximation for noncommuting two pairs of mappings. As consequences, our works generalize the recent works of Nashine [9] by weakening commutativity hypothesis and by increasing the ...

On common fixed points of asymptotically nonexpansive mappings in the intermediate sense [PDF]

open access: yes, 1993
summary:Some strong convergence theorems of common fixed points of asymptotically nonexpansive mappings in the intermediate sense are obtained. The results presented in this paper improve and extend the corresponding results in Huang, Khan and Takahashi,

Fixed points and common fixed points for orbit-nonexpansive mappings in metric spaces [PDF]

open access: yes, 2022
In this paper we introduce an interlacing condition on the elements of a family of operators that allows us to gather together a number of results on fixed points and common fixed points for single and families of mappings defined on metric spaces.

On a Common Jungck Type Fixed Point Result in Extended Rectangular b-Metric Spaces

open access: yesAxioms, 2019
In this paper, we present a Jungck type common fixed point result in extended rectangular b-metric spaces. We also give some examples and a known common fixed point theorem in extended b-metric spaces.

Common fixed points of set-valued mappings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
The main purpose of this paper is to obtain a common fixed point for a pair of set-valued mappings of Greguš type condition. Our theorem extend Diviccaro et al. (1987), Guay et al. (1982), and Negoescu (1989).

The Results of Common Fixed Points in b-Metric Spaces [PDF]

open access: yes, 2023
In this paper, we present some results on the existence and uniqueness of common fixed points on ∗-complete topological spaces. Our results generalize and improve upon earlier results in the literature. Finally, we give some examples in

Fixed points and common points for fundamentally nonexpansive mappings on banach spaces [PDF]

open access: yesJournal of Hyperstructures, 2015
In this paper, we present some fixed point theorems for fundamentally nonexpansive mappings in Banach spaces and give one common fixed point theorem for a commutative family of demiclosed fundamentally nonexpansive mappings on a nonempty weakly compact ...
