对于所有的热点来说都是紧凑的。这种黎曼流形的集合相当大。除了紧致黎曼流形外,该类还包含非紧致黎曼流形,其中对于所有的t b> 0, r EL~(M),我们有(PtqO(x) ~ 0 = x—0(见[12],[5],[7]关于保证这一条件的几何假设的结果)。在这里,我们开始研究H(t)相对于~a, S,,支持的位置,更准确地说,H(t) a的行为是t +oo。
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.
