Uniqueness and pseudolocality theorems of the mean curvature flow

Abstract: Mean curvature flow evolves isometrically immersed base manifolds M in the direction of their mean curvatures in an ambient manifold M . If the base manifold M is compact, the short-time existence and uniqueness of the mean curvature flow are well known. For complete isometrically immersed submanifolds of arbitrary codimensions, the existence and uniqueness are still unsettled even in the Euclidean space. In this paper, we solve the uniqueness problem affirmatively for the mean curvature flow of general codime… Show more

“…Now we prove that there exist κ 0 , r 0 > 0 such that L t is κ 0 -noncollapsed on the scale r 0 for t ∈ [ 1 2 t 0 , t 0 ]. In fact, by Proposition 2.2 in [2] or Theorem 2.1 in [7] the injectivity radius of L is bounded from below…”

“…In [8] one of the main tools in proving this characterization was Perelman's pseudolocality theorem [16,Theorem 10.3]. In [4] the pseudolocality theorem for the mean curvature has been proved which motivated us to prove Theorem 1.5, that is, the following: In the case of mean convex mean curvature flow, we have a stronger result, that is Theorem 1.6. The proof of this theorem is simple so we give it here first.…”
