Abstract:
We show that the generalized hypergeometric function $_2{F_1}$ of matrix argument is the series expansion at the origin of a special case of the hypergeometric function associated with the root system of type $BC$. In addition we prove that the Jacobi polynomials of matrix argument correspond to the Jacobi polynomials associated with the root system of type $BC$. We also give a precise relation between Jack polynomials and the Jacobi polynomials associated with the root system of type $A$. As a side result one obtains generalized hook-length formulas which are related to Harish-Chandra’s ${\mathbf {c}}$-function and one can prove a conjecture due to Macdonald relating two inner products on a space of symmetric functions.References
