Quasi-analytic $L^p$-functions on Riemannian symmetric spaces of noncompact type, a theorem of Chernoff

Abstract

A result of Chernoff gives sufficient condition for an $L^2$-function on ${\mathbb{R}}^n$ to be quasi-analytic. This is a generalization of the classical Denjoy-Carleman theorem on $\mathbb{R}$ and of the subsequent work on ${\mathbb{R}}^n$ by Bochner and Taylor. In this note we endeavour to obtain an exact analogue of the result of Chernoff for $L^p,p\in [1,2]$ functions on the Riemannian symmetric spaces of noncompact type. No restriction on the rank of the symmetric spaces and no condition on the symmetry of the functions is assumed.
