Vector-valued metrics, fixed points and coupled fixed points for nonlinear operators [PDF]

open access: yesFixed Point Theory and Applications, 2013
Abstract In this paper, we will present fixed point theorems for singlevalued and multivalued operators in spaces endowed with vector-valued metrics, as well as a Gnana Bhaskar-Lakshmikantham-type theorem for the coupled fixed point problem, associated to a pair of singlevalued operators (satisfying a generalized mixed monotone property) in ...

Fixed point and coupled fixed point theorems on b-metric-like spaces [PDF]

open access: yesJournal of Inequalities and Applications, 2013
Abstract We first introduce the concept of b-metric-like space which generalizes the notions of partial metric space, metric-like space and b-metric space. Then we establish the existence and uniqueness of fixed points in a b-metric-like space as well as in a partially ordered b-metric-like space.

Coupled fixed point sets with data-dependence and stability [PDF]

open access: yesSurveys in Mathematics and its Applications, 2022
In this paper we establish a coupled fixed point theorem of a coupled multivalued mapping defined on a complete metric space. In our result we use a new contractive inequality. There are rational terms in the expression of the inequality. The contractive

Coupled fixed point theorems under new coupled implicit relation in Hilbert spaces

open access: yesDemonstratio Mathematica, 2022
The aim of this paper is to study existence and uniqueness of coupled fixed point for a family of self-mappings satisfying a new coupled implicit relation in a Hilbert space. We also prove well-posedness of a coupled fixed point problem.

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.

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 ...
