Variation of Fixed-Point and Coincidence Sets [PDF]
Journal of the Australian Mathematical Society. Series A. Pure Mathematics and Statistics, 1988 AbstractTopologise the set of continuous self-mappings of a Hausdorff space by the graph topology. When the set of closed subsets of the space is given the upper semi-finite topology then the function which assigns to a map its fixed-point set is continuous. In many familiar cases this is the largest such topology.

On common fixed point of generalized contractive mappings in metric spaces [PDF]
Surveys in Mathematics and its Applications, 2012 Existence of common fixed points is established for two self-mappings satisfying a generalized contractive condition. The presented results generalize several well known comparable results in the literature. We also study well-posedness of a common fixed

MAPS PRESERVING THE COINCIDENCE POINTS OF OPERATORS
EURASIAN MATHEMATICAL JOURNAL, 2021 Summary: Let \(\mathcal{B(X)}\) be the algebra of all bounded linear operators on a Banach space \(\mathcal{X}\) with \(\dim \mathcal{X} \geqslant 2\). In this paper, we describe surjective maps \(\phi: \mathcal{B(X)}\to\mathcal{B(X)}\) preserving the coincidence points of operators, i.e., \(C(A,B)=C(\phi(A),\phi(B))\), for every \(A, B \in \mathcal{B ...

Coincidence points in uniform spaces [PDF]
International Journal of Mathematics and Mathematical Sciences, 1992 Summary: We give a coincidence point theorem in sequentially complete Hausdorff uniform spaces. Our result reduces to a result of \textit{S. P. Acharya} [Yokohama Math. J. 22, 105-116 (1974; Zbl 0295.54058)].

Relational Meir-Keeler Contractions and Common Fixed Point Theorems
Journal of Function Spaces, 2022 In this article, we prove some coincidence and common fixed point theorems under the relation-theoretic Meir-Keeler contractions in a metric space endowed with a locally finitely T-transitive binary relation.

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 ...

On almost coincidence points in generalized convex spaces
Fixed Point Theory and Applications, 2006 We prove an almost coincidence point theorem in generalized convex spaces. As an application, we derive a result on the existence of a maximal element and an almost coincidence point theorem in hyperconvex spaces.

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 of Weaker Contractions in Partially Ordered Metric Spaces
Journal of Applied Mathematics, 2013 We prove new coincidence point theorems for the -contractions and generalized Meir-Keeler-type --contractions in partially ordered metric spaces. Our results generalize many recent coincidence point theorems in the literature.
