摘要
In this paper we will show that for every positive integer k and each pair of points p, q is an element of M, where M is a Riemannian manifold diffeomorphic to the 2-dimensional sphere, there always exist at least k geodesics connecting p and q of length at most 22kd, where d is the diameter of M.
