Common coupled coincidence and coupled fixed point results in two generalized metric spaces [PDF]

Fixed Point Theory and Applications, 2011
AbstractIn this article, we prove the existence of common coupled coincidence and coupled fixed point of generalized contractive type mappings in the context of two generalized metric spaces. These results generalize several comparable results from the current literature.

Coincidence point results of nonlinear contractive mappings in partially ordered metric spaces

Cubo, 2021
In this paper, we proved some coincidence point results for $f$-nondecreasing self-mapping satisfying certain rational type contractions in the context of a metric space endowed with a partial order.

Coupled coincidence and coupled common fixed point theorem in dislocated quasi metric space

Engineering and Applied Science Letters, 2020
The objective of this paper is to establish a theorem involving a pair of weakly compatible mappings fulfilling a contractive condition of rational type in the context of dislocated quasi metric space. Besides we proved the existence and uniqueness of coupled coincidence and coupled common fixed point for such mappings.

Remarks on some coupled coincidence point results in partially ordered metric spaces

Arab Journal of Mathematical Sciences, 2014
In this paper we have used a method of reducing coupled coincidence and coupled fixed point results in partially ordered metric spaces to the respective results for mappings with one variable, even obtaining (in some cases) more general theorems.

Common fixed point and common coupled fixed point theorems for weakly monotone mappings

Boletim da Sociedade Paranaense de Matemática
In this paper we have established two common fixed point theorems which are variants of the fixed point theorem of Boyd and Wong [On nonlinear contractions, Proc. Amer. Math. Soc. 20(1969), 458-464]. By applying the newly established fixed point theorems two common coupled fixed point theorems have been proved for a pair of weakly increasing mappings ...

Some Remarks on Multidimensional Fixed Point Theorems

, 2014
MARTINEZ-MORENO, JUAN/0000-0002-3340-2781In this paper, we show that most of the multidimensional (including coupled, tripled, quadrupled) fixed point theorems in the context of (ordered) metric spaces are, in fact, immediate consequences of well-known ...

Common Coupled Fixed Point Theorems for a Pair of Sb-metric Spaces

, 2023
In this work, we investigate the existence of common coupled fixed point and coupled coincidence points in a setting of two Sb-metric spaces. Here we use a pair of w-compatible mappings.

Strong Common Coupled Fixed Point Result in Fuzzy Metric Spaces [PDF]

, 2013
Coupled fixed point problems have attracted large attention in recent times. In this paper we have proved a fuzzy coupled fixed point result. Precisely, we have defined the concept of strong coupled fixed point and have established the existence of a ...

A Perov Version of Fuzzy Metric Spaces and Common Fixed Points for Compatible Mappings

Mathematics, 2021
In this paper, we define and study the Perov fuzzy metric space and the topology induced by this space. We prove Banach contraction theorems. Moreover, we devised new results for Kramosil and Michálek fuzzy metric spaces.
