On zeros of discrete orthogonal polynomials [PDF]

open access: yesJournal of Approximation Theory, 2009
AbstractWe exploit difference equations to establish sharp inequalities on the extreme zeros of the classical discrete orthogonal polynomials, Charlier, Krawtchouk, Meixner and Hahn. We also provide lower bounds on the minimal distance between their consecutive zeros.

A Probablistic Origin for a New Class of Bivariate Polynomials [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2008
We present here a probabilistic approach to the generation of new polynomials in two discrete variables. This extends our earlier work on the 'classical' orthogonal polynomials in a previously unexplored direction, resulting in the discovery of an ...

Orthogonal polynomials of a discrete variable and Lie algebras of complex-size matrices [PDF]

open access: green, 2000
We give a uniform interpretation of the classical continuous Chebyshev's and Hahn's orthogonal polynomials of discrete variable in terms of Feigin's Lie algebra gl(N), where N is any complex number.

Discrete Orthogonal Polynomial Expansions of Averaged Functions

open access: bronzeJournal of Mathematical Analysis and Applications, 1995
Abstract Starting from the classical Fourier coefficients of a given function ƒ(x), Boas and Izumi [J. Indian Math. Soc.24 (1960), 191-210] derived an explicit expression for the Fourier coefficients of g(x), or appropriately defined average of ƒ(x). Later, Askey [J. Math. Anal.

Discrete semi-classical orthogonal polynomials: generalized Charlier

open access: bronzeJournal of Computational and Applied Mathematics, 2000
AbstractGeneralized Charlier polynomials are introduced as semi-classical orthogonal polynomials of class 1 with one parameter. Main characteristic data are established from the Laguerre–Freud equations generating the coefficients of the recurrence relation satisfied by the polynomials.

Laguerre–Freud Equations for the Gauss Hypergeometric Discrete Orthogonal Polynomials

open access: yesMathematics, 2023
The Cholesky factorization of the moment matrix is considered for the Gauss hypergeometric discrete orthogonal polynomials. This family of discrete orthogonal polynomials has a weight with first moment given by ρ0=2F1a,bc+1;η.

Comparative asymptotics for discrete semiclassical orthogonal polynomials

open access: yesBulletin of Mathematical Sciences, 2023
We study the ratio [Formula: see text] asymptotically as [Formula: see text], where the polynomials [Formula: see text] are orthogonal with respect to a discrete linear functional and [Formula: see text] denote the falling factorial polynomials.
