Coupled fixed point analysis in fuzzy cone metric spaces with an application to nonlinear integral equations

open access: yesAdvances in Difference Equations, 2020
In this paper, we introduce the concept of coupled type and cyclic coupled type fuzzy cone contraction mappings in fuzzy cone metric spaces. We establish some coupled fixed point results without the mixed monotone property, and also present some coupled ...

Existence of Solutions for a System of Integral Equations Using a Generalization of Darbo’s Fixed Point Theorem

open access: yesMathematics, 2020
In this paper, an extension of Darbo’s fixed point theorem via θ -F-contractions in a Banach space has been presented. Measure of noncompactness approach is the main tool in the presentation of our proofs.

α-Coupled Fixed Points and Their Application in Dynamic Programming [PDF]

open access: yesAbstract and Applied Analysis, 2014
We introduce the definition ofα-coupled fixed point in the space of the bounded functions on a setSand we present a result about the existence and uniqueness of such points. Moreover, as an application of our result, we study the problem of existence and uniqueness of solutions for a class of systems of functional equations arising in dynamic ...

Fixed point theorems for generalized weakly contractive mappings in metric spaces with applications

open access: yesFixed Point Theory and Applications, 2018
In this paper, motivated and inspired by Samet et al., we introduce the notion of generalized weakly contractive mappings in metric spaces and prove the existence and uniqueness of fixed point for such mappings, and we obtain a coupled fixed point ...

Remark on the system of nonlinear variational inclusions

open access: yesArab Journal of Mathematical Sciences, 2014
We prove the existence of a solution to the system of nonlinear variational inclusions problem. We provide examples of applications related to a coupled best approximations theorem for multivalued mappings and a multivalued coupled coincidence point.

Coincidence point theorems for $\varphi$-$\psi$-contraction mappings in metric spaces involving a graph

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2016
Some new coupled coincidence and coupled common fixed point theorems for $\varphi$-$\psi$-contraction mappings are established. We have also an application to some integral system to support the results.
