摘要
Let M be a complete Riemannian manifold which is either compact or has a pole, and let phi be a positive smooth function on M. In the warped product M x R-phi, we study the flow by the mean curvature of a locally Lipschitz continuous graph on M and prove that the flow exists for all time and that the evolving hypersurface is C-infinity for t > 0 and is a graph for all t. Moreover, under certain conditions, the flow has a well-defined limit.
