Journal ArticleDOI
Hausdorff's moment problem and expansions in Legendre polynomials☆
TL;DR: In this paper, a new proof for Hausdorff's condition on a set of moments which determines when the function generating these moments is in L 2 is given, using Legendre polynomials and their discrete extensions found by Tchebychef.
Journal ArticleDOI
Jacobi polynomial expansions with positive coefficients and imbeddings of projective spaces
TL;DR: In this article, Schoenberg's work is used to prove a conjecture about when a Jacobi polynomial Pn(x) can be expanded in terms of another Px) with nonnegative coefficients.
Journal ArticleDOI
The q-harmonic oscillator and an analog of the Charlier polynomials
Richard Askey,Sergeĭ K. Suslov +1 more
TL;DR: A model of a q-harmonic oscillator based on q-Charlier polynomials of Al-Salam and Carlitz is discussed in this paper, where simple explicit realization of q-creation and q-annihilation operators, q-coherent states and an analog of the Fourier transformation are found.
Book ChapterDOI
Vietoris’s Inequalities and Hypergeometric Series
TL;DR: The inequalities of Vietoris have been a good source of problems and new results as mentioned in this paper, and a hypergeometric sum suggested by one of the problems is evaluted in this paper.
