Collocation Method via Jacobi Polynomials for Solving Nonlinear Ordinary Differential Equations

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2011
We extend a collocation method for solving a nonlinear ordinary differential equation (ODE) via Jacobi polynomials. To date, researchers usually use Chebyshev or Legendre collocation method for solving problems in

Breaking Barriers in High‐Order Spectral Methods: The Intrinsic Matrix Approach

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 5, 15 March 2026.
ABSTRACT This paper introduces a unified framework in Hilbert spaces for applying high‐order differential operators in bounded domains using Chebyshev, Legendre, and Fourier spectral methods. By exploiting the banded structure of differentiation matrices and embedding boundary conditions directly into the operator through a scaling law relating ...

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.

Methods Based on Polynomial Chaos for Quadratic Delay Differential Equations With Random Parameters

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.
ABSTRACT We consider systems of delay differential equations (DDEs), including a single delay and a quadratic right‐hand side. In a system, parameters are replaced by random variables to perform an uncertainty quantification. Thus the solution of the DDEs becomes a random process, which can be represented by a series of the generalised polynomial chaos.

INTEGRAL REPRESENTATIONS FOR THE JACOBI–PINEIRO POLYNOMIALS AND THE FUNCTIONS OF THE SECOND KIND

open access: yesПроблемы анализа, 2019
We consider the Hermite – Pad´e approximants for the Cauchy transforms of the Jacobi weights in one interval. The denominators of the approximants are known as Jacobi – Pi˜neiro polynomials.

Analytical properties of the two-variables Jacobi matrix polynomials with applications

open access: yesDemonstratio Mathematica, 2021
In the current study, we introduce the two-variable analogue of Jacobi matrix polynomials. Some properties of these polynomials such as generating matrix functions, a Rodrigue-type formula and recurrence relations are also derived.

Bayesian Adaptive Polynomial Chaos Expansions

open access: yesStat, Volume 15, Issue 1, March 2026.
ABSTRACT Polynomial chaos expansions (PCEs) are widely used for uncertainty quantification (UQ) tasks, particularly in the applied mathematics community. However, PCE has received comparatively less attention in the statistics literature, and fully Bayesian formulations remain rare—especially with implementations in R.

Extended Jacobi polynomials

open access: yesInternational Journal of Contemporary Mathematical Sciences, 2014
In this paper, with the help of generalized hypergeometric functions of the type 4 2 F , an extension of the Jacobi polynomials is established and a number of generating functions similar to those of classical Jacobi polynomials have been proved.
