TiTle:  The dynamical algebra of the superintegrable model on the 2-sphere and two-variable Jacobi polynomials

Abstract:  The dynamical algebra of the generic superintegrable model on S_2 will be introduced. It will be shown to provide an algebraic interpretation of the bivariate Jacobi polynomials. This will offer a framework to review the properties of certain algebras of the Askey-Wilson type that are associated to bispectral hypergeometric polynomials. The covariance of the pentagonal scheme that will have emerged shall be described.
