极小超曲面的Morse指标与第一贝蒂数的比较

Comparing the Morse index and the first Betti number of minimal hypersurfaces

Lucas Ambrozio, Alessandro Carlotto, Ben Sharp

摘要:

通过扩展和推广Ros和Savo以前的工作,我们描述了一种方法,以证明某些正弯曲的环境流形上的每一个封闭的极小超曲面的Morse指数是有界的,从下面的第一个贝蒂数的线性函数。该技术是灵活的,足以证明,这种关系之间的指数和拓扑的极小超曲面举行,例如,在所有紧凑的秩一对称空间,产品的圆与领域的任意尺寸和适当的捏子流形的欧几里得空间。这些结果证实了一个普遍的猜想,由于Schoen和Marques-Neves的一个广泛的类的环境空间。

英文摘要:

By extending and generalising previous work by Ros and Savo, we describe a method to show that the Morse index of every closed minimal hypersurface on certain positively curved ambient manifolds is bounded from below by a linear function of its first Betti number. The technique is flexible enough to prove that such a relation between the index and the topology of minimal hypersurfaces holds, for example, on all compact rank one symmetric spaces, on products of the circle with spheres of arbitrary dimension and on suitably pinched submanifolds of the Euclidean spaces. These results confirm a general conjecture due to Schoen and Marques-Neves for a wide class of ambient spaces.
