A New Generalization of Legendre-Based Appell Polynomials with Two Parameters and Their Applications

Axioms
In the present work, we introduce and study a new two-parameter generalization of Legendre-based Appell polynomials, defined through an explicit representation that unifies classical Legendre structures with the Appell polynomial framework. Starting from

Oceanic Mesoscale Eddy Fitting Using Legendre Polynomial Surface Fitting Model Based on Along-Track Sea Level Anomaly Data

Remote Sensing
Exploring the spatial distribution of sea surface height involves two primary methodologies: utilizing gridded reanalysis data post-secondary processing or conducting direct fitting along-track data.

Circular Bernstein polynomial distributions [PDF]

This paper introduces a new non-parametric approach to the modeling of circular data, based on the use of Bernstein polynomial densities which generalizes the standard Bernstein polynomial model to account for the specific characteristics of circular ...

Solution of polynomial Lyapunov and Sylvester equations

, 2006
A two-variable polynomial approach to solve the one-variable polynomial Lyapunov and Sylvester equations is proposed. Lifting the problem from the one-variable to the two-variable context gives rise to associated lifted equations which live on finite ...

Polynomial differential systems with invariant algebraic curves of arbitrary degree formed by Legendre polynomials

Altres ajuts: Reial Acadèmia de Ciències i Arts de BarcelonaIn 1891 Poincaré asked: Given m ≥ 2, is there a positive integer M(m) such that if a polynomial differential system of degree m has an invariant algebraic curve of degree ≥ M(m), then it has a ...

Parallel Fast Legendre Transform

, 2008
We discuss a parallel implementation of a fast algorithm for the discrete polynomial Legendre transform. We give an introduction to the Driscoll-Healy algorithm using polynomial arithmetic, and present experimental results on the efficiency and accuracy ...
