The real-analytic solutions of the Abel functional equation [PDF]

open access: yesStudia Mathematica, 1999
The authors continue to investigate the Abel equation \[ \phi(Fx)-\phi(x)=1, \qquad x \in X \] where \(\phi:X \to \mathbb R\) is the unknown function, \(X\) is a topological space and \(F:X \to X\) is a continuous mapping. In a previous paper [Stud. Math. 127, No.

Three Positive Periodic Solutions for a Class of Higher-Dimensional Functional Differential Equations with Impulses on Time Scales

open access: yesAdvances in Difference Equations, 2009
By using a multiple fixed point theorem (Avery-Peterson fixed point theorem) for cones, some criteria are established for the existence of three positive periodic solutions for a class of higher-dimensional functional differential equations with impulses

A real-space Green’s function method for the numerical solution of Maxwell’s equations [PDF]

open access: yesCommunications in Applied Mathematics and Computational Science, 2016
Author(s): Lo, B; Minden, V; Colella, P | Abstract: A new method for solving the transverse part of the free-space Maxwell equations in three dimensions is presented. By taking the Helmholtz decomposition of the electric field and current sources and considering only the divergence-free parts, we obtain an explicit real-space representation for the ...

Functional derivatives applied to error propagation of uncertainties in topography to large-aperture scintillometer-derived heat fluxes [PDF]

open access: yesAtmospheric Measurement Techniques, 2014
Scintillometer measurements allow for estimations of the refractive index structure parameter Cn2 over large areas in the atmospheric surface layer. Turbulent fluxes of heat and momentum are inferred through coupled sets of equations derived from the ...

Generalised theory on asymptotic stability and boundedness of stochastic functional differential equations [PDF]

open access: yes, 2011
Asymptotic stability and boundedness have been two of most popular topics in the study of stochastic functional differential equations (SFDEs) (see e.g. Appleby and Reynolds (2008), Appleby and Rodkina (2009), Basin and Rodkina (2008), Khasminskii (1980),
