三维齐性空间中常中曲率曲面的Gauss映射

Gauss maps of constant mean curvature surfaces in three-dimensional homogeneous spaces

Jun-ichi Inoguchi, Joeri Van der Veken

摘要:

众所周知,对于三维实空间形式中的曲面,其中曲率的恒定性等价于高斯映射的调和性。然而,这对于任意三维环境空间中的表面通常不是真的。在本文中,我们研究这个问题的曲面在一个重要的和非常自然的家庭的三维环境空间,即齐性空间。特别地,我们得到了三维齐性空间中Gauss映射满足更温和的垂直调和性条件的常中曲率曲面的完全分类。

英文摘要:

It is well-known that for a surface in a 3-dimensional real space form the constancy of the mean curvature is equivalent to the harmonicity of the Gauss map. However, this is not true in general for surfaces in an arbitrary 3-dimensional ambient space. In this paper we study this problem for surfaces in an important and very natural family of 3-dimensional ambient spaces, namely homogeneous spaces. In particular, we obtain a full classification of constant mean curvature surfaces, whose Gauss map satisfies the more mild condition of vertical harmonicity, in all 3-dimensional homogeneous spaces.
