Classification of hypersurfaces with constant principal curvatures in ${\mathbb{H}}^m\times {\mathbb{H}}^n$

Haizhong Li, Renhao Tan, Zeke Yao

In this paper, we study the hypersurfaces in ${\mathbb{H}}^m\times {\mathbb{H}}^n$ ($m\ge 3,n\ge 2$) with constant principal curvatures. Let $g$ be the number of distinct constant prin…
