In this paper, we study the curve shortening flow in a general Riemannian manifold. We have many results for the global behavior of the flow. In particular, we show the following results: letMbe a compact Riemannian manifold. (1) If the curve shortening flow exists for infinite time, and, then for everyn> 0,. Furthermore, the limiting curve exists and is a closed geodesic inM. (2) InM×S1, if γ0is a ramp, then we have a global flow which converges to a closed geodesic inC∞norm. As an application, we prove the theorem of Lyusternik and Fet.
