$FG$-coupled fixed point theorems in cone metric spaces

Karpatsʹkì Matematičnì Publìkacìï, 2018
The concept of $FG$- coupled fixed point introduced recently is a generalization of coupled fixed point introduced by Guo and Lakshmikantham. A point $(x,y)\in X\times X$ is said to be a coupled fixed point of the mapping $F: X\times X \rightarrow X$ if $

Coupled Fixed Point Results in Complete Partial Metric Spaces [PDF]

International Journal of Mathematics and Mathematical Sciences, 2012
We establish some coupled fixed point theorems for a mapping satisfying some contraction conditions in complete partial metric spaces. Our consequences extend the results of H. Aydi (2011).

An Illusion: “A Suzuki Type Coupled Fixed Point Theorem”

Abstract and Applied Analysis, 2014
We admonish to be careful on studying coupled fixed point theorems since most of the reported fixed point results can be easily derived from the existing corresponding theorems in the literature. In particular, we notice that the recent paper [Semwal and

A Coupled Fixed Point Technique for Solving Coupled Systems of Functional and Nonlinear Integral Equations

Mathematics, 2019
In this paper, we obtain coupled fixed point results for F-contraction mapping satisfying a nonlinear contraction condition in the framework of complete metric space without and with a directed graph. As applications of our results, we study a problem of

Hybrid Coupled Fixed Point Theorems in Metric Spaces with Applications

Journal of Function Spaces, 2019
In this manuscript, using CLR property, coupled coincidence and common coupled fixed point results for two-hybrid pairs satisfying (F,φ)- contraction are demonstrated.

Quadruple fixed point theorems for nonlinear contractions on partial metric spaces

Applied General Topology, 2014
The notion of coupled fixed point was introduced by Guo and Laksmikantham [12]. Later Gnana Bhaskar and Lakshmikantham in [11] investigated the coupled fixed points in the setting of partially ordered set by defining the notion of mixed monotone property.

Some Fixed Point Theorems in Generalized Metric Spaces Endowed with Vector-valued Metrics and Application in Linear and Nonlinear Matrix Equations [PDF]

Sahand Communications in Mathematical Analysis, 2020
Let $mathcal{X}$ be a partially ordered set and $d$ be a generalized metric on $mathcal{X}$. We obtain some results in coupled and coupled coincidence of $g$-monotone functions on $mathcal{X}$, where $g$ is a function from $mathcal{X}$ into itself ...

Coupled Fixed Point Theorem for the Generalized Langevin Equation with Four-Point and Strip Conditions

Advances in Mathematical Physics, 2022
By considering a metric space with partially ordered sets, we employ the coupled fixed point type to scrutinize the uniqueness theory for the Langevin equation that included two generalized orders.
