Bispectral commuting difference operators for multivariable Askey-Wilson polynomials [PDF]

open access: hybrid, 2010
We construct a commutative algebra A z , generated by d algebraically independent q-difference operators acting on variables z 1 , z 2 ,..., z d , which is diagonalized by the multivariable Askey-Wilson polynomials P n (z) considered by Gasper and Rahman

Befriending Askey–Wilson polynomials [PDF]

open access: greenInfinite Dimensional Analysis, Quantum Probability and Related Topics, 2014
We recall five families of polynomials constituting a part of the so-called Askey–Wilson scheme. We do this to expose properties of the Askey–Wilson (AW) polynomials that constitute the last, most complicated element of this scheme. In doing so we express AW density as a product of the density that makes q-Hermite polynomials orthogonal times a ...

Tridiagonal representations of theq-oscillator algebra and Askey–Wilson polynomials [PDF]

open access: green, 2017
A construction is given of the most general representations of the q-oscillator algebra where both generators are tridiagonal. It is shown to be connected to the Askey–Wilson polynomials.

Multiple Askey–Wilson polynomials and related basic hypergeometric multiple orthogonal polynomials [PDF]

open access: green, 2020
We first show how one can obtain Al-Salam--Chihara polynomials, continuous dual $q$-Hahn polynomials, and Askey--Wilson polynomials from the little $q$-Laguerre and the little $q$-Jacobi polynomials by using special transformations.

The Askey–Wilson polynomials and q-Sturm–Liouville problems [PDF]

open access: yesMathematical Proceedings of the Cambridge Philosophical Society, 1994
We find the adjoint of the Askey–Wilson divided difference operator with respect to the inner product on L2(–1, 1, (1– x2)½dx) defined as a Cauchy principal value and show that the Askey-Wilson polynomials are solutions of a q-Sturm–Liouville problem ...

Some transformation formulas associated with Askey-Wilson polynomials and Lassalle's formulas for Macdonald-Koornwinder polynomials [PDF]

open access: green, 2014
We present a fourfold series expansion representing the Askey-Wilson polynomials. To obtain the result, a sequential use is made of several summation and transformation formulas for the basic hypergeometric series, including the Verma's q-extension of ...

Zeros and orthogonality of the Askey-Wilson polynomials for $q$ a root of unity [PDF]

open access: yesDuke Mathematical Journal, 1996
We study some properties of the Askey-Wilson polynomials (AWP) when q is a primitive Nth root of unity. For general four-parameter AWP, zeros of the Nth polynomial and the orthogonality measure are found explicitly.

On the Askey-Wilson and Rogers Polynomials [PDF]

open access: bronzeCanadian Journal of Mathematics, 1988
The q-shifted factorial (a)n or (a; q)n isand an empty product is interpreted as 1. Recently, Askey and Wilson [6] introduced the polynomials1.1where1.2and1.3We shall refer to these polynomials as the Askey-Wilson polynomials or the orthogonal 4ϕ3 polynomials. They generalize the 6 — j symbols and are the most general classical orthogonal polynomials, [

Turán Inequalities for Symmetric Askey-Wilson Polynomials [PDF]

open access: bronzeRocky Mountain Journal of Mathematics, 2000
The authors study a renormalized \(A-W\) polynomial \(V_n(x)\). Using the Szász technique they establish the inequalities \[ 0\leq V_n^2(x)-V_{n+1} (x)V_{n-1} (x)\leq K, \] where \(K\) is independent of \(x\). The two inequalities hold under certain conditions upon parameters and variable.
