Coupled coincidence point technique and its application for solving nonlinear integral equations in RPOCbML spaces

open access: yes, 2020
The aim of this paper is to obtain some new important consequences related to coupled coincidence points via C-class functions in the context of a regular partial ordered complete b -metric-like space (for short, RPOCbML space); this space arises from ...

Exclusive Hong-Ou-Mandel zero-coincidence point [PDF]

open access: yesPhysical Review A, 2019
A generalized multi-parameter Hong-Ou-Mandel interferometer is presented which extends the conventional "Mandel dip" configuration to the case where a symmetric biphoton source is used to monitor the contemporary presence of k independent time-delays ...

Fixed point results of $(\phi,\psi)$-weak contractions in ordered $b$-metric spaces

open access: yesCubo, 2022
The purpose of this paper is to prove some results on fixed point, coincidence point, coupled coincidence point and coupled common fixed point for the mappings satisfying generalized $(\phi, \psi)$-contraction conditions in complete partially ordered ...

Near-coincidence point results in metric interval space and hyperspace via simulation functions

open access: yes, 2020
Recently, Wu (Mathematics 6(11):219, 2018 ; Mathematics 6(6):90, 2018 ) introduced the concept of a near-fixed point and established some results on near fixed points in a metric interval space and hyperspace.

Coincidence points of mappings in Banach spaces [PDF]

open access: yesFixed Point Theory, 2020
In this article we prove an existence theorem for coincidence points of mappings in Banach spaces. This theorem generalizes the Kantorovich fixed point theorem.

Probabilistic (ω,γ,ϕ)-contractions and coupled coincidence point results

open access: yesAIMS Mathematics, 2021
In this paper, we introduce the notion of probabilistic $ (\omega, \gamma, \phi) $-contraction and establish the existence coupled coincidence points for mixed monotone operators subjected to the introduced contraction in the framework of ordered Menger $

Approximate Coincidence Point of Two Nonlinear Mappings

open access: yesJournal of Mathematics, 2013
We study the approximate coincidence point of two nonlinear functions introduced by Geraghty in 1973 and Mizoguchi and Takahashi (ℳ𝒯-function) in 1989.

On Changing Fixed Points and Coincidences to Roots [PDF]

open access: yesProceedings of the American Mathematical Society, 1992
The coincidence problem, finding solutions to f ( x ) = g ( x ) f(x) = g(x) , can sometimes be converted to a root problem, finding solutions to σ ( x ) = a \sigma (x) = a .

Common Best Proximity Coincidence Point Theorem for Dominating Proximal Generalized Geraghty in Complete Metric Spaces

open access: yes, 2020
In this paper, we introduce a new concept of dominating proximal generalized Geraghty for two mappings and prove the existence and uniqueness of a common best proximity coincidence point in complete metric spaces.

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

open access: yesArab 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.
