摘要
If is a bounded real valued continuous function which has a unique maximum or a unique minimum at a point and if the inverse image of the neighborhoods of f(x (0)) shrinks regularly to x (0), then is a dense subset of where f (m) (x)=f(x) (m) and {e (i) } is the natural basis of . The result extends to all homogeneous groups, Riemannian symmetric spaces of noncompact type, Damek-Ricci spaces etc.
