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].

Common Coincidence Points and Common Fixed Points in Fuzzy Semi-Metric Spaces

Mathematics, 2018
We propose the so-called fuzzy semi-metric space in which the symmetric condition is not assumed to be satisfied. In this case, there are four kinds of triangle inequalities that should be considered.

New Existence Results and Generalizations for Coincidence Points and Fixed Points without Global Completeness [PDF]

Abstract and Applied Analysis, 2013
Some new existence theorems concerning approximate coincidence point property and approximate fixed point property for nonlinear maps in metric spaces without global completeness are established in this paper.

Asymptotically Coupled Coincidence Points and Asymptotically Coupled Fixed Points in Fuzzy Semi-Metric Spaces

Axioms, 2022
Asymptotically coupled coincidence points and asymptotically coupled fixed points in fuzzy semi-metric spaces are studied in this paper. The fuzzy semi-metric space is taken into account, which lacks symmetric conditions.

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 ...

Continuous Dependence of Coincidence Points on a Parameter

Set-Valued and Variational Analysis, 2014
In the paper, the authors consider the coincidence points existence problem with a parameter in metric spaces. They give sufficient conditions for the dependence of a coincidence point on the parameter to be continuous, Hölder continuous, or Lipschitz continuous.

Coincidence Points in Generalized Metric Spaces

Set-Valued and Variational Analysis, 2014
The authors continue the research (see [\textit{A. V. Arutyunov}, Dokl. Math. 76, No. 2, 665--668 (2007; Zbl 1152.54351); translation from Dokl. Akad. Nauk, Ross. Akad. Nauk 416, No. 2, 151--155 (2007)]) on coincidence points for maps (single-valued and set-valued) such that one of them is \(\beta\)-Lipschitz continuous and the second one is an ...

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 $

Positive coincidence points for a class of nonlinear operators and their applications to matrix equations

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 ...
