## Spherical Functions and MVOP's associated to the pair (SU(2)xSU(2),diag)

*Maarten van Pruijssen*

Matrix valued orthogonal polynomials (MVOP's) rarely come from group theory, as opposed to ordinary orthogonal polynomials. In this talk I discuss how to construct families of MVOP's out of the spherical functions associated to the pair (SU(2)xSU(2),diag).
