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.

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

Continuous Dependence of Coincidence Points on a Parameter
Set-Valued and Variational Analysis, 2020 The coincidence points existence problem with a parameter is considered. Sufficient conditions for dependence of a coincidence point on a parameter to be continuous, Hölder continuous or Lipschitz continuous are obtained.

Coincidence Points in Generalized Metric Spaces
Set-Valued and Variational Analysis, 2020 Covering mappings in generalized metric spaces are considered. The coincidence points theorems for single-valued and set-valued mappings are proved. The results obtained are applied to the problem of solvability of equations in the space of continuous ...

On coincidence points for vector mappings
Russian Mathematics, 2020 For mappings acting in the product of metric spaces we propose a concept of vector covering. This concept is a natural extension of the notion of covering formappings inmetric spaces. The statements on the solvability of systems of operator equations are

On the structure of the set of coincidence points
Sbornik: Mathematics, 2020 We consider the set of coincidence points for two maps between metric spaces. Cardinality, metric and topological properties of the coincidence set are studied.
