Uniformization of higher genus finite type log-Riemann surfaces

Abstract

We consider a log-Riemann surface $\mathcal{S}$ with a finite number of ramification points and finitely generated fundamental group. The log-Riemann surface is equipped with a local holomorphic difffeomorphism $π: \mathcal{S} \to \C$. We prove that $\mathcal{S}$ is biholomorphic to a compact Riemann surface with finitely many punctures $S$, and the pull-back of the 1-form $d\pi$ under the biholomorphic map $\varphi :S\to \mathcal{S}$ is a 1-form $\omega ={\varphi }^{\ast }d\pi$ with isolated singularities at the punctures of exponential type, i.e. near each puncture $p$, $\omega =e^h\cdot {\omega }_0$ where $h$ is a function meromorphic near $p$ and ${\omega }_0$ a 1-form meromorphic near $p$.
