. Upon solving a finite discrete reduction of the difference Heun equation, we arrive at an elliptic generalization of the Racah polynomials. We exhibit the three-term recurrence relation and the orthogonality relations for these elliptic Racah polynomials. The well-known q -Racah polynomials of Askey and Wilson are recovered as a trigonometric limit.

Continuous biorthogonality of the elliptic hypergeometric function

We construct a family of continuous biorthogonal functions related to an elliptic analogue of the Gauss hypergeometric function. The key tools used for that are the elliptic beta integral and the

A Set of Orthogonal Polynomials That Generalize the Racah Coefficients or 6 - j Symbols.

A very general set of orthogonal polynomials with five free parameters is given explicitly, the orthogonality relation is proved and the three term recurrence relation is found.

Elliptic U(2) Quantum Group and Elliptic Hypergeometric Series

We investigate an elliptic quantum group introduced by Felder and Varchenko, which is constructed from the R-matrix of the Andrews–Baxter–Forrester model, containing both spectral and dynamical

Elliptic Kac–Sylvester Matrix from Difference Lamé Equation

Through a finite-dimensional reduction of the difference Lamé equation, an elliptic analog of the Kac–Sylvester tridiagonal matrix is found. We solve the corresponding finite discrete Lamé equation

Quantum integrability of the generalized elliptic Ruijsenaars models

The quantum integrability of the generalized elliptic Ruijsenaars models is shown. These models are mathematically related to the Macdonald operator and the Macdonald - Koornwinder operator, which

Sklyanin invariant integration

The Sklyanin algebra admits realizations by difference operators acting on theta functions. Sklyanin found an invariant metric for the action and conjectured an explicit formula for the corresponding

Orthogonal Polynomials, Duality and Association Schemes

This paper reconstructs and characterizes the Askey–Wilson orthogonal polynomials as those having duals (in the sense of Delsarte) which are also orthogonal. It introduces the concepts of eigenvalues

Conserved operators of the generalized elliptic Ruijsenaars models

We construct the integrable families of the generalized elliptic Ruijsenaars models by use of the Yang–Baxter equation and the reflection equation. The higher order conserved operators of these

Spectral Transformation Chains and Some New Biorthogonal Rational Functions

Abstract:A discrete-time chain, associated with the generalized eigenvalue problem for two Jacobi matrices, is derived. Various discrete and continuous symmetries of this integrable equation are

The Elliptic Painlevé Lax Equation vs. van Diejen's 8-Coupling Elliptic Hamiltonian

The 8-parameter elliptic Sakai difference Painleve equation admits a Lax formulation. We show that a suitable specialization of the Lax equation gives rise to the time-independent Schrodinger
