Sparse polynomial approximation of parametric elliptic PDEs. Part I: affine coefficients [PDF]

open access: yes, 2016
We consider elliptic partial differential equations with diffusion coefficients that depend affinely on countably many parameters. We study the summability properties of polynomial expansions of the function mapping parameter values to solutions of the ...

The continous Legendre transform, its inverse transform, and applications

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1980
This paper is concerned with the continuous Legendre transform, derived from the classical discrete Legendre transform by replacing the Legendre polynomial Pk(x) by the function Pλ(x) with λ real. Another approach to T.M. MacRobert's inversion formula is

B meson decay constants f(Bc), f(Bs) and f(B) from QCD sum rules [PDF]

open access: yes, 2014
Finite energy QCD sum rules with Legendre polynomial integration kernels are used to determine the heavy meson decay constant f(Bc), and revisit f(B) and f(Bs).

Discrete Hypergeometric Legendre Polynomials [PDF]

open access: yesMathematics, 2021
A discrete analog of the Legendre polynomials defined by discrete hypergeometric series is investigated. The resulting polynomials have qualitatively similar properties to classical Legendre polynomials. We derive their difference equations, recurrence relations, and generating function.
