给定一个高亏格的曲面,我们将考察该曲面的TeichMuller空间的Weil-Petersson完备性,并研究映射类群在其上的等距作用。主要的观察结果是集合的几何特征与非紧对称空间上的半单李群作用的几何特征具有很强的相似性。
Given a surface of higher genus, we will look at the Weil-Petersson completion of the Teichmuller space of the surface, and will study the isometric action of the mapping class group on it. The main observation is that the geometric characteristics of the setting bear strong similarities to the ones in semi-simple Lie group actions on noncompact symmetric spaces.
