关于$S^k$的极小超曲面的交

On the intersection of minimal hypersurfaces of $S^k$

Renan Assimos

摘要:

自Frankel的工作以来,已知在具有正里奇曲率的流形中,两个紧浸入极小超曲面必有交点。这个结果的几个推广可以在文献中找到,例如在Lawson,Petersen和Wilhelm等人的作品中。在$S^k$的极小超曲面的特殊情况下,我们证明了Frankel定理的一个更强的版本.也就是说,如果给定$S^k$的两个紧致极小超曲面$M_1$,$M_2$和一个点$\mathbf{p}\in S^k$,则$M_1$和$M_2$在关于$\mathbf{p}$的半球上有交点.作为该结果的推论,对于一般维度的情况,我们给出了Ros关于$S^3$极小曲面的两片性质的另一种证明。

英文摘要:

It is known since the work of Frankel that two compactly immersed minimal hypersurfaces in a manifold with positive Ricci curvature must have an intersection point. Several generalizations of this result can be found in the literature, for example in the works of Lawson, Petersen and Wilhelm, among others. In the special case of minimal hypersurfaces of $S^k$, we prove a stronger version of Frankel's theorem. Namely, we show that if two compact minimal hypersurfaces $M_1$, $M_2$ of $S^k$ and a point $\mathbf{p}\in S^k$ are given, then $M_1$ and $M_2$ have an intersection point in the hemisphere with respect to $\mathbf{p}$. As a corollary of this result, we give an alternative proof to Ros' two-piece property of minimal surfaces of $S^3$, for the general dimension case.
