具有一般低熵初始数据的平均曲率流

Mean curvature flow with generic low-entropy initial data

Otis Chodosh, Kyeongsu Choi, Christos Mantoulidis, Felix Schulze

AI总结:

本文证明低熵闭超曲面可扰动为平均曲率流仅产生球形与圆柱形奇点,并借此改进 Bernstein-Wang 低熵 Schoenflies 型定理,同时用新密度下降论证重证八维面积极小超曲面的一般正则性。

摘要:

我们证明了,熵足够低的闭超曲面可以经过扰动,使其平均曲率流只遇到球形和圆柱形奇点。我们的定理适用于 $\mathbb{R}^3$ 中所有熵 $\leq 2$ 的闭曲面,以及 $\mathbb{R}^4$ 中所有熵 $\leq λ(\mathbb{S}^1 \times \mathbb{R}^2)$ 的闭超曲面。结合 Daniels-Holgate 近期的工作,这通过将熵界放宽至 $λ(\mathbb{S}^1 \times \mathbb{R}^2)$,强化了 Bernstein-Wang 的低熵 Schoenflies 型定理。我们基于一种新颖的密度下降论证的技术,还给出了八维面积极小超曲面一般正则性结果(归功于 Hardt-Simon 和 Smale)的新证明。

英文摘要:

We prove that sufficiently low-entropy closed hypersurfaces can be perturbed so that their mean curvature flow encounters only spherical and cylindrical singularities. Our theorem applies to all closed surfaces in $\mathbb{R}^3$ with entropy $\leq 2$ and to all closed hypersurfaces in $\mathbb{R}^4$ with entropy $\leq λ(\mathbb{S}^1 \times \mathbb{R}^2)$. When combined with recent work of Daniels-Holgate, this strengthens Bernstein-Wang's low-entropy Schoenflies-type theorem by relaxing the entropy bound to $λ(\mathbb{S}^1 \times \mathbb{R}^2)$. Our techniques, based on a novel density drop argument, also lead to a new proof of generic regularity result for area-minimizing hypersurfaces in eight dimensions (due to Hardt-Simon and Smale).
