Abstract
In this paper, we establish L-p local uncertainty principle for the Fourier transform; and we deduce L-p version of Heisenberg-Pauli-Weyl uncertainty principle. We use also the L-p local uncertainty principle, the partial Fourier integrals and the techniques of Donoho-Stark, we present two uncertainty principles of concentration type in the L-p theory, when 1 < p = 2. Some numerical applications are given.
