Some coupled fixed point theorems in cone Sb-metric space

, 2020
In this paper, we extend the definition of coupled fixed point to mappings on cone Sb-metric space and prove some coupled fixed point theorems. Our results extend the coupled fixed point results of F. Sabetghadam et al. [Some coupled fixed point theorems

Coupled fixed point results for new classes of functions on ordered vector metric space

Acta Mathematica Hungarica
The contraction condition in the Banach contraction principle forces a function to be continuous. Many authors overcome this obligation and weaken the hypotheses via metric spaces endowed with a partial order. In this paper, we present some coupled fixed

Coupled fixed point theorems in partially ordered metric spaces

Advances in Fixed Point Theory, 2019
In this paper we prove coupled fixed point theorems of multivalued mappings in partially ordered metric spaces by utilizing the combination of multivalued monotone iterative technique and multivalued contraction principle.

On generalized coupled fixed points with applications to the solvability of coupled systems of nonlinear quadratic integral equations

, 2018
In this paper, we introduce the notion of generalized coupled fixed points and, as a consequence of Darbo’s fixed point theorem associated to an abstract measure of noncompactness, we present a result about the existence of this class of coupled fixed ...

Some Coupled Coincident Point Theorems in Metric Space

Fuzzy Optimization and Modeling, 2022
In this present work, we prove coupled coincident point theorem for contractive mappings F:X×X⟶X and g:X⟶X such that F(X×X)⊆g(X) in metric spaces that have a nonempty F- invariant and g-invariant complete subset and we prove uniqueness coupled ...

On Coupled Fixed Point Theorems for Nonlinear Contractions in Partially Ordered -Metric Spaces

Abstract and Applied Analysis, 2012
Two concepts—one of the coupled fixed point and the other of the generalized metric space—play a very active role in recent research on the fixed point theory.

Some Rational Coupled Fuzzy Cone Contraction Theorems in Fuzzy Cone Metric Spaces with an Application

Journal of Mathematics, 2021
In this paper, we establish the new concept of rational coupled fuzzy cone contraction mapping in fuzzy cone metric spaces and prove some unique rational-type coupled fixed-point theorems in the framework of fuzzy cone metric spaces by using “the ...
