Uncertainty principles for the Schrödinger equation on Riemannian symmetric spaces of the noncompact type
Annales de l'Institut Fourier, Volume 62 (2012) no. 3, p. 859-886
Let X be a Riemannian symmetric space of the noncompact type. We prove that the solution of the time-dependent Schrödinger equation on X with square integrable initial condition f is identically zero at all times t whenever f and the solution at a time t 0 >0 are simultaneously very rapidly decreasing. The stated condition of rapid decrease is of Beurling type. Conditions respectively of Gelfand-Shilov, Cowling-Price and Hardy type are deduced.
Soit X un espace riemannien symétrique de type non-compact. On montre que la solution de l’équation de Schrödinger dépendante du temps sur X, avec condition initiale de carré intégrable f, est nulle en tout temps t lorsque f et la solution à un temps t 0 >0 donné sont simultanément très rapidement décroissantes. La condition de décroissance rapide considérée est de type Beurling. Des conditions respectivement de types Gelfand-Shilov, Cowling-Price et Hardy en sont déduites.
