摘要:
In this note we prove the backwards uniqueness of the mean curvature flow for (codimension one) hypersurfaces in a Euclidean space. More precisely, let F-t, (F) over tilde (t):M-n -> Rn+1 be two complete solutions of the mean curvature flow on M-n x [0, T] with bounded second fundamental forms. Suppose F-T = (F) over tilde (T), then F-t = (F) over tilde (t) on M-n x [0, T]. This is an analog of a result of Kotschwar on the Ricci flow.
