复双曲空间中李超曲面的曲率性质

Curvature properties of Lie hypersurfaces in the complex hyperbolic space

Tatsuyoshi Hamada, Yuji Hoshikawa, Hiroshi Tamaru

摘要:

复双曲空间中的李超曲面是不含焦点子流形的齐次实超曲面。复双曲空间中的所有李超曲面的集合在一个闭区间上是双射的,这给出了齐次超曲面从直纹极小超曲面到时球面的变形.本文研究了李超曲面的内蕴几何,如里奇曲率、数量曲率和截曲率。

英文摘要:

A Lie hypersurface in the complex hyperbolic space is a homogeneous real hypersurface without focal submanifolds. The set of all Lie hypersurfaces in the complex hyperbolic space is bijective to a closed interval, which gives a deformation of homogeneous hypersurfaces from the ruled minimal one to the horosphere. In this paper, we study intrinsic geometry of Lie hypersurfaces, such as Ricci curvatures, scalar curvatures, and sectional curvatures.
