欧几里得空间中几乎脐闭超曲面的定量振动估计

Quantitative oscillation estimates for almost-umbilical closed hypersurfaces in Euclidean space

Julian Scheuer

摘要:

在无迹第第二基本型比中曲率小$δ$的假设下,证明了欧几里得空间中超曲面对球面的$ε$-贴近性.在具有有界体积的一致凸超曲面类中,给出了$δ$对$ε$的显式依赖性.

英文摘要:

We prove $ε$-closeness of hypersurfaces to a sphere in Euclidean space under the assumption that the traceless second fundamental form is $δ$-small compared to the mean curvature. We give the explicit dependence of $δ$ on $ε$ within the class of uniformly convex hypersurfaces with bounded volume.
