Abstract

We consider a log-Riemann surface S\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:S\C\pi : \mathcal{S} \to \C. We prove that S\mathcal{S} is biholomorphic to a compact Riemann surface with finitely many punctures SS, and the pull-back of the 1-form dπd\pi under the biholomorphic map ϕ:SS\phi : S \to \mathcal{S} is a 1-form ω=ϕdπ\omega = \phi^* d\pi with isolated singularities at the punctures of exponential type, i.e. near each puncture pp, ω=ehω0\omega = e^h \cdot \omega_0 where hh is a function meromorphic near pp and ω0\omega_0 a 1-form meromorphic near pp.
