Common fixed point theorems in modular G-metric spaces [PDF]

open access: yes, 2013
The purpose of this paper is to prove the existence of the unique common fixed point theorems of a pair of weakly compatible mappings satisfying $\Phi$-maps in modular G-metric ...

Common fixed points for semigroups of mappings [PDF]

open access: yesProceedings of the American Mathematical Society, 1973
Let X be a compact convex subset of a strictly convex Banach space. Let S be a Hausdorff topological semigroup which is either left amenable or left reversible. Then for any generalised nonexpansive (jointly) continuous action of S on X, X contains a common fixed point of S.

Fixing Nonconvergence of Algebraic Iterative Reconstruction with an Unmatched Backprojector [PDF]

open access: yes, 2019
We consider algebraic iterative reconstruction methods with applications in image reconstruction. In particular, we are concerned with methods based on an unmatched projector/backprojector pair; i.e., the backprojector is not the exact adjoint or ...

On common fixed points of mappings [PDF]

open access: yesBulletin of the Australian Mathematical Society, 1974
The object of this paper is to study common fixed points of mappings of a complete metric space into itself. The results obtained are generalizations of Ray Theorems.

Fixed point and common fixed point results in ordered cone metric spaces

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2012
In this paper we establish some fixed point results for functions which satisfy certain weak contractive inequalities in partially ordered cone metric spaces. We have also given some illustrative examples.

Common Fixed Point Theorems in Non-archimedean Fuzzy Metric Spaces [PDF]

open access: yes, 2012
The aim of this paper is to define the concept of weakly comparable multi-valued mappings. Also we obtain some common fixed point theorems for pairs of weakly comparable multi-valued mappings in ordered non-Archimedean fuzzy metric ...

A self-adaptive inertial subgradient extragradient method for pseudomonotone equilibrium and common fixed point problems

open access: yesFixed Point Theory and Applications, 2020
In this paper, we introduce a self-adaptive inertial subgradient extragradient method for solving pseudomonotone equilibrium problem and common fixed point problem in real Hilbert spaces.

Some common fixed point theorem of rational contractive mappings in dislocated metric spaces

open access: yesTopological Algebra and its Applications, 2023
We improve the rational contractive condition and prove the common fixed point in the dislocated metric spaces. In addition, the new generalized rational contraction has existence of a common solution for a system of integral equations.

Fixed Point and Common Fixed Point Theorems on Ordered Cone b-Metric Spaces

open access: yesAbstract and Applied Analysis, 2013
The concept of a cone b-metric space has been introduced recently as a generalization of a b-metric space and a cone metric space in 2011. The aim of this paper is to establish some fixed point and common fixed point theorems on ordered cone b-metric ...

Parrondo's dynamic paradox for the stability of non-hyperbolic fixed points [PDF]

open access: yes, 2017
We show that for periodic non-autonomous discrete dynamical systems, even when a common fixed point for each of the autonomous associated dynamical systems is repeller, this fixed point can became a local attractor for the whole system, giving rise to a ...
