R^n中极小超曲面的指数与拓扑

Index and topology of minimal hypersurfaces in R^n

Chao Li

摘要:

本文研究了$\mathbb{R}^n$中具有有限全曲率的浸入双边极小超曲面。证明了超曲面的Morse指标与Jacobi算子的零值之和由其端点数与第一个贝蒂数的线性函数自下而上有界.当$n=4$时,我们能够通过对刚性情况的仔细研究来删除零项。我们的结果是李王的第一个有效推广。利用我们的指数估计和Chodosh-Ketover-Maximo最近工作的思想,我们证明了具有有限指数的$\mathbb{R}^4$中极小超曲面的紧性和有限性结果.

英文摘要:

In this paper, we consider immersed two-sided minimal hypersurfaces in $\mathbb{R}^n$ with finite total curvature. We prove that the sum of the Morse index and the nullity of the Jacobi operator is bounded from below by a linear function of the number of ends and the first Betti number of the hypersurface. When $n=4$, we are able to drop the nullity term by a careful study for the rigidity case. Our result is the first effective generalization of Li-Wang. Using our index estimates and ideas from the recent work of Chodosh-Ketover-Maximo, we prove compactness and finiteness results of minimal hypersurfaces in $\mathbb{R}^4$ with finite index.
