黎曼流形中的高余维中曲率流

Mean curvature flow of higher codimension in Riemannian manifolds

Kefeng Liu, Hongwei Xu, Entao Zhao

摘要:

研究了有界几何黎曼流形中任意余维中曲率流的收敛性。证明了如果初始子流形满足一个拼挤条件,则该子流形沿中曲率流在有限时间内光滑收缩到一个圆点。由此得到了黎曼流形中子流形的一个可微球面定理。

英文摘要:

We investigate the convergence of the mean curvature flow of arbitrary codimension in Riemannian manifolds with bounded geometry. We prove that if the initial submanifold satisfies a pinching condition, then along the mean curvature flow the submanifold contracts smoothly to a round point in finite time. As a consequence we obtain a differentiable sphere theorem for submanifolds in a Riemannian manifold.
