Predictable projections of conformal stochastic integrals: an application to Hermite series and to Widder's representation

open access: yes, 2011
In this article, we study predictable projections of stochastic integrals with respect to the conformal Brownian motion, extending the connection between powers of the conformal Brownian motion and the corresponding Hermite polynomials.

PERICLES: A Set of Empirical Rotational Isochrones Modeled on Cool Dwarfs in Open Clusters and Wide Binaries

open access: yesAstronomische Nachrichten, Volume 347, Issue 1, January 2026.
ABSTRACT Isochrones, equal‐age curves, are widely used in astrophysics to estimate stellar ages. Classical stellar parameters are, however, very limited in their usability for main sequence stars because of their weak age‐dependence. Here, rotation period measurements provide complementary information.

Forced Periodic Reactor Operation Applied to Methanol Synthesis

open access: yesChemCatChem, Volume 18, Issue 2, 28 January 2026.
Forced periodic operation of methanol synthesis is studied theoretically and experimentally considering an industrial Cu/ZnO/Al2O3 catalyst. The nonlinear frequency response method and rigorous mathematical optimization predict attractive forcing parameters.

Polynomially oscillatory multipliers on Gelfand–Shilov spaces

open access: yesMathematische Nachrichten, Volume 299, Issue 1, Page 35-59, January 2026.
Abstract We study continuity of the multiplier operator eiq$\text{e}^{\text{i} q}$ acting on Gelfand–Shilov spaces, where q$q$ is a polynomial on Rd$\mathbf {R}^{d}$ of degree at least two with real coefficients. In the parameter quadrant for the spaces, we identify a wedge that depends on the polynomial degree for which the operator is continuous.

Some Identities on Bernoulli and Hermite Polynomials Associated with Jacobi Polynomials

open access: yesDiscrete Dynamics in Nature and Society, 2012
We investigate some identities on the Bernoulli and the Hermite polynomials arising from the orthogonality of Jacobi polynomials in the inner product space Pn.

Asymptotics of integrals of Hermite polynomials [PDF]

open access: yes, 2010
Integrals involving products of Hermite polynomials with the weight factor exp (−x2) over the interval (−∞,∞) are considered. A result of Azor, Gillis and Victor (SIAM J. Math. Anal.

On the Stability Barrier of Hermite Type Discretizations of Advection Equations

open access: yesNumerical Methods for Partial Differential Equations, Volume 42, Issue 1, January 2026.
ABSTRACT We establish a stability barrier for a class of high‐order Hermite‐type discretization of 1D advection equations underlying the hybrid‐variable (HV) and active flux (AF) methods. These methods approximate both cell averages and nodal solutions and evolve them in time simultaneously.

A Hermite Polynomial Approach for Solving the SIR Model of Epidemics

open access: yesMathematics, 2018
In this paper, the problem of the spread of a non-fatal disease in a population is solved by using the Hermite collocation method. Mathematical modeling of the problem corresponds to a three-dimensional system of nonlinear ODEs.
