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

open access: yes, 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 Survey on q-Polynomials and their Orthogonality Properties [PDF]

open access: yes, 2010
In this paper we study the orthogonality conditions satisfied by the classical q-orthogonal polynomials that are located at the top of the q-Hahn tableau (big q-jacobi polynomials (bqJ)) and the Nikiforov-Uvarov tableau (Askey-Wilson polynomials (AW ...

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.

A finite quantum oscillator model related to special sets of Racah polynomials [PDF]

open access: yes, 2016
In [R. Oste and J. Van der Jeugt, arXiv: 1507.01821 [math-ph]] we classified all pairs of recurrence relations in which two (dual) Hahn polynomials with different parameters appear.

Some results on biorthogonal polynomials

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1994
Some biorthogonal polynomials of Hahn and Pastro are derived using a polynomial modification of the Lebesgue measure dθ combined with analytic continuation. A result is given for changing the measures of biorthogonal polynomials on the unit circle by the

Bivariate Hahn moments for image reconstruction

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2014
This paper presents a new set of bivariate discrete orthogonal moments which are based on bivariate Hahn polynomials with non-separable basis. The polynomials are scaled to ensure numerical stability.

Quantum state transfer in spin chains with q-deformed interaction terms [PDF]

open access: yes, 2010
We study the time evolution of a single spin excitation state in certain linear spin chains, as a model for quantum communication. Some years ago it was discovered that when the spin chain data (the nearest neighbour interaction strengths and the ...

Three-fold symmetric Hahn-classical multiple orthogonal polynomials [PDF]

open access: greenAnalysis and Applications, 2019
We characterize all the multiple orthogonal three-fold symmetric polynomial sequences whose sequence of derivatives is also multiple orthogonal. Such a property is commonly called the Hahn property and it is an extension of the concept of classical polynomials to the context of multiple orthogonality.

Some Laguerre-Hahn Orthogonal Polynomials of Class One

open access: yesAsia Pacific Journal of Mathematics, 2018
Summary: Let \(u(\beta_0)\) be the regular form fulfilling \((u(\beta_0))_{2n+1}=\beta_0(u(\beta_0))_{2n}\), \(n\geq 0\) where \(\beta_0\) is an arbitrary complex number in such a way that for \(\beta_0=0\) one has the symmetric forms. Recently, the symmetric Laguerre-Hahn forms (when \(\beta_0=0\)) of class \(s\leq1\) are determined. In this paper, we
