投影结构、嫁接和测量叠层

Projective structures, grafting, and measured laminations

David Dumas, Michael Wolf

摘要:

我们发现,嫁接任何固定的双曲曲面定义了一个同胚从空间的测量叠层Teichmuller空间,补充的结果Scannell-Wolf嫁接固定的叠层。利用这一结果研究了曲面上复射影($\CP^1$)结构空间的复解析坐标系与几何坐标系之间的关系。我们还研究了Teichmuller空间中与嫁接坐标相关的射线,获得极值和双曲长度函数及其衍生物沿这些嫁接射线的估计。

英文摘要:

We show that grafting any fixed hyperbolic surface defines a homeomorphism from the space of measured laminations to Teichmuller space, complementing a result of Scannell-Wolf on grafting by a fixed lamination. This result is used to study the relationship between the complex-analytic and geometric coordinate systems for the space of complex projective ($\CP^1$) structures on a surface. We also study the rays in Teichmuller space associated to the grafting coordinates, obtaining estimates for extremal and hyperbolic length functions and their derivatives along these grafting rays.
