Resumen:
The random walk to be considered takes place in the - spherical dual of the group U(n + 1), for a xed nite dimensional irreducible representation  of U(n). The transition matrix comes from the three term recursion relation satis ed by a sequence of matrix valued orthogonal polynomials built up from the irreducible spherical functions of type  of SU(n + 1). One of the stochastic models is an urn model and the other is a Young diagram model.
