Quasi-exactly solvable problems and the dual (q-)Hahn polynomials [PDF]

open access: green, 1999
A second-order differential (q-difference) eigenvalue equation is constructed whose solutions are generating functions of the dual (q-)Hahn polynomials. The fact is noticed that these generating functions are reduced to the (little q-)Jacobi polynomials,

Hahn, Jacobi, and Krawtchouck polynomials of several variables [PDF]

open access: greenarXiv, 2013
Hahn polynomials of several variables can be defined by using the Jacobi polynomials on the simplex as a generating function. Starting from this connection, a number of properties for these two families of orthogonal polynomials are derived. It is shown that the Hahn polynomials appear as connecting coefficients between several families of orthogonal ...

Constructing Krall-Hahn orthogonal polynomials [PDF]

open access: green, 2014
Given a sequence of polynomials $(p_n)_n$, an algebra of operators $\mathcal A$ acting in the linear space of polynomials and an operator $D_p\in \mathcal A$ with $D_p(p_n)=\theta_np_n$, where $\theta_n$ is any arbitrary eigenvalue, we construct a new ...

Hahn polynomials for hypergeometric distribution [PDF]

open access: yesAdv. in Appl. Math. 139 (2022), Paper No. 102364, 34pp, 2020
Orthogonal polynomials for the multivariate hypergeometric distribution are defined on lattices in polyhedral domains in $\RR^d$. Their structures are studied through a detailed analysis of classical Hahn polynomials with negative integer parameters ...

Two $q$-operational equations and Hahn polynomials [PDF]

open access: yesarXiv, 2022
Motivated by Liu's recent work in \cite{Liu2022}. We shall reveal the essential feature of Hahn polynomials by presenting two new $q$-exponential operators. These lead us to use a systematic method to study identities involving Hahn polynomials.

The multivariate Hahn polynomials and the singular oscillator [PDF]

open access: green, 2015
Karlin and McGregor's d-variable Hahn polynomials are shown to arise in the (d+1)-dimensional singular oscillator model as the overlap coefficients between bases associated to the separation of variables in Cartesian and hyperspherical coordinates. These

Orthogonal polynomials and Laurent polynomials related to the Hahn-Exton q-Bessel function [PDF]

open access: yesarXiv, 1995
Laurent polynomials related to the Hahn-Exton $q$-Bessel function, which are $q$-analogues of the Lommel polynomials, have been introduced by Koelink and Swarttouw.

A high order $q$-difference equation for $q$-Hahn multiple orthogonal polynomials [PDF]

open access: green, 2009
A high order linear $q$-difference equation with polynomial coefficients having $q$-Hahn multiple orthogonal polynomials as eigenfunctions is given. The order of the equation is related to the number of orthogonality conditions that these polynomials ...

A Discrete Cramér–Von Mises Statistic Related to Hahn Polynomials with Application to Goodness-of-Fit Testing for Hypergeometric Distributions [PDF]

open access: goldAxioms
We give the Karhunen–Loève expansion of the covariance function of a family of discrete weighted Brownian bridges, appearing as discrete analogues of continuous Gaussian processes related to Cramér –von Mises and Anderson–Darling statistics. This analogy

Dual -1 Hahn polynomials: "classical" polynomials beyond the Leonard duality [PDF]

open access: green, 2011
We introduce the -1 dual Hahn polynomials through an appropriate $q \to -1$ limit of the dual q-Hahn polynomials. These polynomials are orthogonal on a finite set of discrete points on the real axis, but in contrast to the classical orthogonal ...
