Hypersurfaces of $H^{2} \times H^{2}$ with constant sectional curvature

Haizhong Li, Luc Vrancken, Xianfeng Wang +1

In this paper, we classify the hypersurfaces of $H^{2} \times H^{2}$ with constant sectional curvature. In contrast to $S^{2} \times S^{2}$ , the resulting e…

On Hopf hypersurfaces of the complex hyperbolic quadric with constant principal curvatures

Haizhong Li, Hiroshi Tamaru, Zeke Yao

In this paper, we study the Hopf hypersurfaces of the complex hyperbolic quadric $Q^{m *} = S O_{2, m}^{o} / (S O_{2} \times S O_{m})$ ( $m \geq 3$ ) with constant principal curvatures. We classify th…

On Hopf hypersurfaces of the complex quadric with constant principal curvatures

Haizhong Li, Hiroshi Tamaru, Zeke Yao

In this paper, we classify the Hopf hypersurfaces of the complex quadric $Q^{m} = S O_{m + 2} / (S O_{2} S O_{m})$ ( $m \geq 3$ ) with at most five distinct constant principal curvatures. We also clas…
