An alternative approach to averaging in nonlinear systems using classical probability density

open access: yesZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 104, Issue 6, June 2024.
Abstract The averaging method is a widely used technique in the field of nonlinear differential equations for effectively reducing systems with “fast” oscillations overlaying “slow” drift. The method involves calculating an integral, which can be straightforward in some cases but can also require simplifications such as series expansions. We propose an

Properties and applications of generalized 1-parameter 3-variable Hermite-based Appell polynomials

open access: yesAIMS Mathematics
We present a novel framework for introducing generalized 3-variable 1-parameter Hermite-based Appell polynomials. These polynomials are characterized by generating function, series definition, and determinant definition, elucidating their fundamental ...

Investigation of piroctone olamine delivery to the skin from single, binary and ternary solvent systems

open access: yesInternational Journal of Cosmetic Science, Volume 46, Issue 3, Page 357-367, June 2024.
To our knowledge, this is the first study to examine the permeation behaviour of OPX for a range of single, binary and ternary solvent systems in human skin in vitro. The findings reported serve to further optimize vehicles that promote deposition of OPX on and in the skin.

Deformation in the large of some complex manifolds, II

open access: yes, 2005
The compact complex manifolds considered in this article are principal torus bundles over a torus. We consider the Kodaira Spencer map of the complete Appell Humbert family (introduced by the first author in Part I) and are able to show that we obtain in

Line defect half-indices of SU(N) Chern-Simons theories

open access: yesJournal of High Energy Physics
We study the Wilson line defect half-indices of 3d N $$ \mathcal{N} $$ = 2 supersymmetric SU(N) Chern-Simons theories of level k ≤ – N with Neumann boundary conditions for the gauge fields, together with 2d Fermi multiplets and fundamental 3d chiral ...

Special values of Gauss's hypergeometric series derived from Appell's series $F_1$ with closed forms

open access: yes, 2016
In a previous work ([Eb]), the author proposed a method employing contiguity relations to derive hypergeometric series in closed form. In [Eb], this method was used to derive Gauss's hypergeometric series $_2F_1$ possessing closed forms. Here, we consider the application of this method to Appell's hypergeometetric series $F_1$ and derive several $F_1 ...
