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 ...

Common fixed, coupled coincidence and common coupled fixed point results in hyperbolic valued metric spaces

open access: yesBoletim da Sociedade Paranaense de Matemática, 2022
In this paper, we obtain existence of unique common fixed point for a contraction mapping on hyperbolic valued metric spaces, and also develop some coupled coincidence point and common coupled fixed point results for two mappings satisfying various ...

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 ...

Compatible mappings and common fixed points (2) [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1986
A common fixed point theorem of S.L. and S.P. Singh is generalized by weakening commutativity hypotheses and by increasing the number of functions involved.

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.

Fixed points, selections and common fixed points for nonexpansive-type mappings

open access: yesJournal of Mathematical Analysis and Applications, 2011
AbstractWe study the existence of fixed points in the context of uniformly convex geodesic metric spaces, hyperconvex spaces and Banach spaces for single and multivalued mappings satisfying conditions that generalize the concept of nonexpansivity. Besides, we use the fixed point theorems proved here to give common fixed point results for commuting ...

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.
