Abstract: This paper investigates the stability of positive definite functions on locally compact groups under one parameter groups of automorphisms. As an application of this it is shown that the only probability distributions on ${R^n}$ which are stable under the full automorphism group $\text {GL}(n,R)$ of ${R^n}$ are the nondegenerate Gaussian distributions. It is furthermore shown that there are no nondegenerate probability distributions of ${R^n}$ which are stable under ${\text {SL}}(n,R)$.
