Discussion on “Multidimensional Coincidence Points” via Recent Publications [PDF]
Abstract and Applied Analysis, 2014 We show that some definitions of multidimensional coincidence points are not compatible with the mixed monotone property. Thus, some theorems reported in the recent publications (Dalal et al., 2014 and Imdad et al., 2013) have gaps. We clarify these gaps

Open Mathematics, 2020 Consider an ordered Banach space and f,gf,g two self-operators defined on the interior of its positive cone. In this article, we prove that the equation f(X)=g(X)f(X)=g(X) has a positive solution, whenever f is strictly α\alpha -concave g-monotone or ...

A novel approach to coincidence point results via proximal contractions with application [PDF]
Scientific ReportsIn this manuscript, we established coincidence point theory by using F-contractions within complete extended suprametric spaces. The results about coincidence points involve $$(F_{\mathbb {C}_{P}})_{\tau }$$ -proximal contractions together with rational $

Coincidence Best Proximity Points of Proximal Berinde G-Contractions
Journal of MathematicsRecently, a concept of proximal Berinde contractions was introduced and applied to prove the existence of coincidence best proximity points in metric spaces. In this article, we established a new approach to show that these results can be obtained from a

Some Common Fixed Points Theorems of Four Weakly Compatible Mappings in Metric Spaces
مجلة بغداد للعلوم, 2021 In this paper, we proved coincidence points theorems for two pairs mappings which are defined on nonempty subset in metric spaces by using condition (1.1). As application, we established a unique common fixed points theorems for these mappings by using

Method of search functionals and its applications in fixed point and coincidence theory
Современная математика: Фундаментальные направления, 2023 The paper contains a survey of several results from the author’s papers and joint papers by the author and Yu. N. Zakharyan, both on the zero existence and approximation for single-valued and multivalued (α, β)-search functionals, and also on the zero ...

A Random Coincidence Point Theorem
Journal of Mathematical Analysis and Applications, 2000 Let \((\Omega ,\Sigma)\) be a measurable space, \(M\) a weakly compact subset of a Banach space \(X\), \(f:\Omega\times M\to M\) and \(T:\Omega\times M\to 2^{M}\) random operators. The main result of this note gives sufficient conditions for the existence of a random coincidence point of \(T\) and \(f\), i.e., a measurable mapping \(\xi:\Omega\to M ...

Coincidence of Fixed Points with Mixed Monotone Property
مجلة بغداد للعلوم, 2023 The purpose of this paper is to introduce and prove some coupled coincidence fixed point theorems for self mappings satisfying -contractive condition with rational expressions on complete partially ordered metric spaces involving altering distance ...

Coincident-point rigidity in normed planes
Ars Mathematica Contemporanea, 2023 A bar-joint framework $(G,p)$ is the combination of a graph $G$ and a map $p$ assigning positions, in some space, to the vertices of $G$. The framework is rigid if every edge-length-preserving continuous motion of the vertices arises from an isometry of the space.

Subcommuting and comparable iterative roots of order preserving homeomorphisms [PDF]
Arab Journal of Mathematical Sciences, 2020 It is known that the iterative roots of continuous functions are not necessarily unique, if it exist. In this note, by introducing the set of points of coincidence, we study the iterative roots of order preserving homeomorphisms.
