关于$\mathbb{S}^2\times\mathbb{S}^2$的超曲面

On hypersurfaces of $\mathbb{S}^2\times\mathbb{S}^2$

Francisco Urbano

摘要:

对$\mathbb{S}^2\times\mathbb{S}^2$的齐次超曲面和等参超曲面进行了分类。在分类中,除了超曲面$\mathbb{S}^1(r)\times\mathbb{S}^2,\,r\in (0,1]$之外,还出现了一类具有三个不同的常数主曲率和零Gauss-Kronecker曲率的超曲面。对至多具有两个常主曲率的$\mathbb{S}^2\times\mathbb{S}^2$的超曲面进行了分类,并在一定条件下对具有三个常主曲率的超曲面进行了分类.

英文摘要:

We classify the homogeneous and isoparametric hypersurfaces of $\mathbb{S}^2\times\mathbb{S}^2$. In the classification, besides the hypersurfaces $\mathbb{S}^1(r)\times\mathbb{S}^2,\,r\in (0,1]$, it appears a family of hypersurfaces with three different constant principal curvatures and zero Gauss-Kronecker curvature. Also we classify the hypersurfaces of $\mathbb{S}^2\times\mathbb{S}^2$ with at most two constant principal curvatures and, under certain conditions, with three constant principal curvatures.
