Coincident-point rigidity in normed planes

open access: yesArs 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.

A Random Coincidence Point Theorem

open access: yesJournal 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 ...

Subcommuting and comparable iterative roots of order preserving homeomorphisms [PDF]

open access: yesArab 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.

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

open access: yesArab 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 ...

Fixed points and coincidence points for multimaps with not necessarily bounded images

open access: yesFixed Point Theory and Applications, 2004
In metric spaces, single-valued self-maps and multimaps with closed images are considered and fixed point and coincidence point theorems for such maps have been obtained without using the (extended) Hausdorff metric, thereby generalizing many results in

Coincidence points principle for mappings in partially ordered spaces

open access: yes, 2020
The concept of covering (regularity) for mappings in partially ordered spaces is introduced. Sufficient conditions for the existence of coincidence points and minimal coincidence points of isotone and orderly covering mappings are obtained. These results

On almost coincidence points in generalized convex spaces

open access: yesFixed 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.

Common coincidence points for Nadler’s type hybrid fuzzy contractions

open access: yesJournal of Inequalities and Applications, 2023
In the framework of complete metric spaces, the major objective of this paper is to investigate if a common coincidence point exists for more than two fuzzy mappings meeting the criteria of hybrid fuzzy contractions of Nadler’s type in connection with ...

Coincidence points of mappings in Banach spaces [PDF]

open access: yesFixed Point Theory, 2020
In this article we prove an existence theorem for coincidence points of mappings in Banach spaces. This theorem generalizes the Kantorovich fixed point theorem.
