Abstract
In this paper, we prove an L-p version of Donoho-Stark's uncertainty principle for the inverse of the hypergeometric Fourier transform on R-d. Next, using the ultracontractive properties of the semigroups generated by the Heckman-Opdam Laplacian operator, we obtain an L-p Heisenberg-Pauli-Weyl uncertainty principle for the inverse of the hypergeometric Fourier transform on R-d.
