Automorphism groups of origami curves
Abstract
A closed Riemann surface (of genus at least one) is called an origami curve if it admits a non-constant holomorphic map with at most one branch value, where is a genus one Riemann surface. In this case, is called an origami pair and is the group of conformal automorphisms of such that . Let be a finite group. It is a known fact that can be realized as a subgroup of for a suitable origami pair . It is also known that can be realized as a group of conformal automorphisms of a Riemann surface of genus and with quotient orbifold also of genus . Given a conformal action of on a surface as before, we prove that there is an origami pair , where has genus and such that the actions of on and that of on are topologically equivalent.
