几何Schotkky群与具有无限亏格的非紧双曲曲面

Geometric Schotkky groups and non compact hyperbolic surface with infinite genus

John A. Arredondo, Camilo Ramírez Maluendas

摘要:

非紧Riemann曲面的拓扑型是由它的端点空间和具有无限亏格的端点所决定的。本文对具有$s$端点的非紧Riemann曲面$S_{m,s}$和它们的具有无限亏格的$m$,使得$m,s\in \mathbb{N}$和$1<m\leq s$,给出了Fuchsian(几何Schottky)群$Γ_{m,s}$的生成元的无限集的精确刻画,使得商空间$\mathbb{H}/ Γ_{m, s}$同胚于$S_{m,s}$,且具有无限大的面积.对于这种结构,我们展示了一个双曲多边形的无限多的边,并给出了一个集合的莫比乌斯变换识别双方对。

英文摘要:

The topological type of a non-compact Riemann surface is determined by its ends space and the ends having infinite genus. In this paper for a non-compact Riemann Surface $S_{m,s}$ with $s$ ends and exactly $m$ of them with infinite genus, such that $m,s\in \mathbb{N}$ and $1<m\leq s$, we give a precise description of the infinite set of generators of a Fuchsian (geometric Schottky) group $Γ_{m,s}$ such that the quotient space $\mathbb{H}/ Γ_{m, s}$ is homeomorphic to $S_{m,s}$ and has infinite area. For this construction, we exhibit a hyperbolic polygon with an infinite number of sides and give a collection of Mobius transformations identifying the sides in pairs.
