曲面群化为SO(2,n)的极大表示的几何

The geometry of maximal representations of surface groups into SO(2,n)

Brian Collier, Nicolas Tholozan, Jérémy Toulisse

摘要:

本文研究了曲面群到秩为2的埃尔米特李群的极大表示的几何和动力学性质。结合希格斯束理论,Anosov表示理论和伪黎曼几何的工具,我们得到了各种感兴趣的结果。我们证明了这些表示是holonomies的某些几何结构,恢复结果Guichard和Wienhard。我们还证明了它们的长度谱是均匀大于一个适当选择的Fuchsian表示,扩展了第二作者以前的工作。最后,我们表明,这些表示保持一个唯一的极小曲面的对称空间,延长拉布里定理Hitchin表示秩2。

英文摘要:

In this paper, we study the geometric and dynamical properties of maximal representations of surface groups into Hermitian Lie groups of rank 2. Combining tools from Higgs bundle theory, the theory of Anosov representations, and pseudo-Riemannian geometry, we obtain various results of interest. We prove that these representations are holonomies of certain geometric structures, recovering results of Guichard and Wienhard. We also prove that their length spectrum is uniformly bigger than that of a suitably chosen Fuchsian representation, extending a previous work of the second author. Finally, we show that these representations preserve a unique minimal surface in the symmetric space, extending a theorem of Labourie for Hitchin representations in rank 2.
