Analysis. In particular are studied the properties of zonal polynomials, seen as spherical functions of a classical Gelfand … pair. A duality formula allows to write the zonal polynomials as spherical functions of a finite Gelfand pair. Finally a … combinatorial technique for the calculation of the zonal polynomials shows that these are the analogous, in the non-central Wishart …
