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 ...

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.

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.

Geometric and homotopy theoretic methods in Nielsen coincidence theory

open access: yes, 2006
In classical fixed point and coincidence theory the notion of Nielsen numbers has proved to be extremely fruitful. Here we extend it to pairs (f_1, f_2) of maps between manifolds of arbitrary dimensions. This leads to estimates of the minimum numbers MCC(

Sensitivity of the IceCube Detector to Astrophysical Sources of High Energy Muon Neutrinos [PDF]

open access: yes, 2003
We present the results of a Monte-Carlo study of the sensitivity of the planned IceCube detector to predicted fluxes of muon neutrinos at TeV to PeV energies.

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.

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.

Coincidence Points of Weaker Contractions in Partially Ordered Metric Spaces

open access: yesJournal 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.

Nonstabilized Nielsen coincidence invariants and Hopf--Ganea homomorphisms

open access: yes, 2006
In classical fixed point and coincidence theory the notion of Nielsen numbers has proved to be extremely fruitful. We extend it to pairs (f_1,f_2) of maps between manifolds of arbitrary dimensions, using nonstabilized normal bordism theory as our main ...
