三维双曲空间中Weingarten曲面的一个刻划

A characterization of Weingarten surfaces in hyperbolic 3-space

Nikos Georgiou, Brendan Guilfoyle

摘要:

本文研究了三维双曲空间中定向测地线空间${\mathbb{L}}({\mathbb{H}}^3)$的二维子流形,它具有典型的中性Kähler结构.这样的曲面是拉格朗日曲面当且仅当在${\mathbb{H}}^3$中存在与$Σ$的测地线正交的曲面。证明了${\mathbb{L}}({\mathbb{H}}^3)$中Lagrange曲面上的诱导度规具有零Gauss曲率当且仅当${\mathbb{H}}^3$中的正交曲面是Weingarten:第二基本型的特征值是函数相关的.然后,我们在${\mathbb{L}}({\mathbb{H}}^3)$中的全零曲面进行分类,并恢复了${\mathbb{H}}^3$中的平坦和CMC 1曲面的全纯构造。

英文摘要:

We study 2-dimensional submanifolds of the space ${\mathbb{L}}({\mathbb{H}}^3)$ of oriented geodesics of hyperbolic 3-space, endowed with the canonical neutral Kähler structure. Such a surface is Lagrangian iff there exists a surface in ${\mathbb{H}}^3$ orthogonal to the geodesics of $Σ$. We prove that the induced metric on a Lagrangian surface in ${\mathbb{L}}({\mathbb{H}}^3)$ has zero Gauss curvature iff the orthogonal surfaces in ${\mathbb{H}}^3$ are Weingarten: the eigenvalues of the second fundamental form are functionally related. We then classify the totally null surfaces in ${\mathbb{L}}({\mathbb{H}}^3)$ and recover the well-known holomorphic constructions of flat and CMC 1 surfaces in ${\mathbb{H}}^3$.
