Localization of Multi-Dimensional Wigner Distributions
arXiv:1007.1796 · doi:10.1063/1.3486068
Abstract
A well known result of P. Flandrin states that a Gaussian uniquely maximizes the integral of the Wigner distribution over every centered disc in the phase plane. While there is no difficulty in generalizing this result to higher-dimensional poly-discs, the generalization to balls is less obvious. In this note we provide such a generalization.
