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.

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.

Coupled Coincidence and Common Fixed Point Theorems for Set-valued and Single-valued Mappings in fuzzy Metric Space [PDF]

open access: yes, 2012
In this paper, we define the tangential property and the generalized coincidence property for a pair of set-valued and single-valued mappings and use it to prove some coupled coincidence and common fixed point theorems for a hybrid pair of mappings ...

New Quasi-Coincidence Point Polynomial Problems

open access: yesJournal of Applied Mathematics, 2013
Let F:ℝ×ℝ→ℝ be a real-valued polynomial function of the form F(x,y)=as(x)ys+as-1(x)ys-1+⋯+a0(x), where the degree s of y in F(x,y) is greater than or equal to 1.

Relational Meir-Keeler Contractions and Common Fixed Point Theorems

open access: yesJournal 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.

open access: yesProceedings of the American Mathematical Society, 1986
We discuss Browder’s coincidence theorem and derive a saddle point theorem from it.

Localized intersection of currents and the Lefschetz coincidence point theorem

open access: yes, 2015
We introduce the notion of a Thom class of a current and define the localized intersection of currents. In particular we consider the situation where we have a smooth map of manifolds and study localized intersections of the source manifold and currents ...

Substitution Delone Sets with Pure Point Spectrum are Inter Model Sets

open access: yes, 2009
The paper establishes an equivalence between pure point diffraction and certain types of model sets, called inter model sets, in the context of substitution point sets and substitution tilings.

Common fixed points for generalized contractive mappings in cone metric spaces [PDF]

open access: yes, 2012
The purpose of this paper is to establish coincidence point and common fixed point results for four maps satisfying generalized weak contractions in cone metric spaces.
