WebThe proof of the latter case is based on the obser-vation that the Fourier transform of functions of fixed A"-type can be expressed in terms of modified Jacobi functions. This approach can be expanded to cover all hyperbolic spaces and also yields a new proof of Hardy's uncertainty principle for all the Rieman-nian symmetric spaces of rank 1. philippine motorcycle
