of "hot spots" is compact for all t > 0. The collection of such Riemannian manifolds is reasonably large. Besides the compact ones, the class contains those noncompact Riemannian manifolds for which for all t > 0, r EL~(M), we have (PtqO(x) ~ 0 as x --oo (see [ 12], [5], [7] for results on the geometric hypotheses guaranteeing this condition). Here we initiate a study of the location of H(t) relative to the support of ~a, S,, and, more precisely, the behavior of H(t) a s t t +oo.
