Bers同时单值化与庞加莱和乐簇的交

Bers' simultaneous uniformization and the intersection of Poincare holonomy varieties

Shinpei Baba

AI总结:

本文研究具有相同和乐的不同$\u2102P^1$-结构有序对空间,证明其到泰希米勒空间乘积去对角线的映射是完备局部分歧覆盖,重证Bers同时单值化定理,并得出任意两个庞加莱和乐簇的交为非空离散集的结论。

摘要:

我们研究黎曼曲面(任意定向)上具有相同和乐的不同$\u2102P^1$-结构的有序对空间,由此拟富克斯空间可等同于该空间的一个连通分支。该空间全纯映射到泰希米勒空间的乘积去掉其对角线的集合。\n 本文证明该映射是完备的局部分歧覆盖映射。作为推论,我们无需任何拟共形形变理论,重新证明了Bers同时单值化定理。我们的核心定理是:任意两个庞加莱和乐簇(${\rm SL}_2\u2102$-opers)的交是非空离散集,这与上述映射密切相关。

英文摘要:

We consider the space of ordered pairs of distinct $\mathbb{C}P^1$-structures on Riemann surfaces (of any orientations) which have identical holonomy, so that the quasi-Fuchsian space is identified with a connected component of this space. This space holomorphically maps to the product of the Teichmüller spaces minus its diagonal. In this paper, we prove that this mapping is a complete local branched covering map. As a corollary, we reprove Bers' simultaneous uniformization theorem without any quasi-conformal deformation theory. Our main theorem is that the intersection of arbitrary two Poincaré holonomy varieties (${\rm SL}_2\mathbb{C}$-opers) is a non-empty discrete set, which is closely related to the mapping.
