A characterization of the Rogers q-hermite polynomials

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1995
In this paper we characterize the Rogers q-Hermite polynomials as the only orthogonal polynomial set which is also đť’źq-Appell where đť’źq is the Askey-Wilson finite difference operator.

Orthogonal Basic Hypergeometric Laurent Polynomials

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2012
The Askey-Wilson polynomials are orthogonal polynomials in$x = cos heta$, which are given as a terminating $_4phi_3$ basic hypergeometric series. The non-symmetric Askey-Wilson polynomials are Laurent polynomials in $z=e^{iheta}$, which are given as a ...

Properties of some families of hypergeometric orthogonal polynomials in several variables

open access: yes, 1996
Limiting cases are studied of the Koornwinder-Macdonald multivariable generalization of the Askey-Wilson polynomials. We recover recently and not so recently introduced families of hypergeometric orthogonal polynomials in several variables consisting of ...

Two Families of Associated Wilson Polynomials [PDF]

open access: bronzeCanadian Journal of Mathematics, 1990
AbstractTwo families of associated Wilson polynomials are introduced. Both families are birth and death process polynomials, satisfying the same recurrence relation but having different initial conditions. Contiguous relations for generalized hypergeometric functions of the type 7F6 are derived and used to find explicit representations for the ...

On Solutions of Holonomic Divided-Difference Equations on Nonuniform Lattices

open access: yesAxioms, 2013
The main aim of this paper is the development of suitable bases that enable the direct series representation of orthogonal polynomial systems on nonuniform lattices (quadratic lattices of a discrete or a q-discrete variable). We present two bases of this

Exact results and Schur expansions in quiver Chern-Simons-matter theories

open access: yesJournal of High Energy Physics, 2020
We study several quiver Chern-Simons-matter theories on the three-sphere, combining the matrix model formulation with a systematic use of Mordell’s integral, computing partition functions and checking dualities.

Nonsymmetric Askey–Wilson polynomials and Q-polynomial distance-regular graphs

open access: bronzeJournal of Combinatorial Theory, Series A, 2016
In his famous theorem (1982), Douglas Leonard characterized the $q$-Racah polynomials and their relatives in the Askey scheme from the duality property of $Q$-polynomial distance-regular graphs. In this paper we consider a nonsymmetric (or Laurent) version of the $q$-Racah polynomials in the above situation.

Bethe Ansatz Solutions to Quasi Exactly Solvable Difference Equations

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2009
Bethe ansatz formulation is presented for several explicit examples of quasi exactly solvable difference equations of one degree of freedom which are introduced recently by one of the present authors.
