Title: Two-variable Meixner polynomials and a discrete model of the two-dimensional harmonic oscillator with $su(2)$ symmetry

Abstract:

The algebraic interpretation of multivariate Meixner polynomials in terms of representations of the pseudo-orthogonal groups will be presented. It will be used to construct a discrete model of the isotropic two-dimensional oscillator that will prove superintegrable.
