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.

New Quasi-Coincidence Point Polynomial Problems [PDF]

open access: yesJournal of Applied Mathematics, 2013
LetF:ℝ×ℝ→ℝbe a real-valued polynomial function of the formF(x,y)=as(x)ys+as-1(x)ys-1+⋯+a0(x), where the degreesofyinF(x,y)is greater than or equal to1. For arbitrary polynomial functionf(x)∈ℝ[x],x∈ℝ, we will find a polynomial solutiony(x)∈ℝ[x]to satisfy the following equation: (*):F(x,y(x))=af(x), wherea∈ℝis a constant depending on the solutiony(x ...

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

open access: yesAxioms, 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.

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

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 ...

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

open access: yesMathematics, 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.

Some results on coincidence points [PDF]

open access: yesBulletin of the Australian Mathematical Society, 1999
In this paper we prove some coincidence point theorems for nonself single-valued and multivalued maps satisfying a nonexpansive condition. These extend fixed point theorems for multivalued maps of a number of authors.

An application of KKM-map principle

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1992
The following theorem is proved and several fixed point theorems and coincidence theorems are derived as corollaries. Let C be a nonempty convex subset of a normed linear space X, f:C→X a continuous function, g:C→C continuous, onto and almost quasi ...
