Coincidence points in uniform spaces [PDF]

International Journal of Mathematics and Mathematical Sciences, 1993
In this note, we give a coincidence point theorem in sequentially complete Hausdorff uniform spaces. Our result reduces to a result of Acharya [1].

Coincidence and fixed points of nonlinear Hybrid contractions [PDF]

International Journal of Mathematics and Mathematical Sciences, 1989
In this Der, we show the existence of solutions of functional equations fx∈sx∩tx and x=fx∈sx∩Tx under certain contraction and asymptotic regularity conditions, where f, S and T are single-valued and multl-valued mappings on a metric space, respectively ...

A novel approach to coincidence point results via proximal contractions with application [PDF]

Scientific Reports
In 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 $

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 ...

Nonunique Coincidence Point Results via Admissible Mappings [PDF]

Journal of Function Spaces, 2021
This paper is aimed at presenting some coincidence point results using admissible mapping in the framework of the partialb-metric spaces. Observed results of the article cover a number of existing works on the topic of “investigation of nonunique fixed points.” We express an example to indicate the validity of the observed outcomes.

Generalized cyclic contractions and coincidence points involving a control function on partial metric spaces [PDF]

Arab Journal of Mathematical Sciences, 2021
Purpose – In this paper, we use the notion of cyclic representation of a nonempty set with respect to a pair of mappings to obtain coincidence points and common fixed points for a pair of self-mappings satisfying some generalized contraction- type ...

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 ...
