双曲三维流形的Weil-Petersson度量和重正化体积

The Weil-Petersson metric and the renormalized volume of hyperbolic 3-manifolds

Kirill Krasnov, Jean-Marc Schlenker

摘要:

我们调查的重正化体积的双曲3-流形,作为一种工具,Teichmuller理论,使用简单的微分几何参数,以恢复有时首先通过其他手段实现的结果。一个这样的应用是麦克马伦的准Fuchsian(或更一般的Kleinian)互惠性,提出了不同的论点。另一个事实是,拟Fuchsian(或更一般的几何有限)双曲三维流形的重整化体积为Teichmuller空间上的Weil-Petersson度量提供了Kahler势。另一个事实是嫁接映射是辛的,这是证明了使用双曲型端定义的重整化体积的一个变体。

英文摘要:

We survey the renormalized volume of hyperbolic 3-manifolds, as a tool for Teichmuller theory, using simple differential geometry arguments to recover results sometimes first achieved by other means. One such application is McMullen's quasifuchsian (or more generally Kleinian) reciprocity, for which different arguments are proposed. Another is the fact that the renormalized volume of quasifuchsian (or more generally geometrically finite) hyperbolic 3-manifolds provides a Kahler potential for the Weil-Petersson metric on Teichmuller space. Yet another is the fact that the grafting map is symplectic, which is proved using a variant of the renormalized volume defined for hyperbolic ends.
