GHMC anti-de Sitter结构模空间上的黎曼度量

Riemannian metrics on the moduli space of GHMC anti-de Sitter structures

Andrea Tamburelli

摘要:

在这篇短文中,我们解释了如何将$\mathrm{SL}(3,\mathbb{R})$ -Hitchin分量上的两个黎曼度量的构造适应于全局双曲反de Sitter结构的变形空间:压力度量和Loftin度量(由李琼玲研究)。我们证明了前者是退化的,并刻画了它的退化轨迹,而后者是无处退化的,Fuchsian轨迹是Teichmüller空间的一个完全测地线的拷贝,并赋予Weil-Petersson度量的倍数.

英文摘要:

In this short note we explain how to adapt the construction of two Riemannian metrics on the $\mathrm{SL}(3,\mathbb{R})$-Hitchin component to the deformation space of globally hyperbolic anti-de Sitter structures: the pressure metric and the Loftin metric (studied by Qiongling Li). We show that the former is degenerate and we characterize its degenerate locus, whereas the latter is nowhere degenerate and the Fuchsian locus is a totally geodesic copy of Teichmüller space endowed with a multiple of the Weil-Petersson metric.
