Purely non-free actions on Riemann surfaces
Rubén A. Hidalgo, Jhony S. Leyca
A group of conformal automorphisms of a Riemann surface is said to act purely non-free, or to produce a gpnf-action, if each of its finite-order elements has fixed points. It is kn…
Cyclic-Schottky strata of Schottky space
Ruben A. Hidalgo, Milagros Izquierdo
Schottky space , where is an integer, is a connected complex orbifold of dimension ; it provides a parametrization of the ${\rm PSL}_{2}({\math…
Extending finite free actions of surfaces
Rubén A. Hidalgo
We prove the existence of finite groups of orientation-preserving homeomorphisms of some closed orientable surface that act freely and which extends as a group of homeomorphism…
Geometric description of Virtual Schottky groups
Ruben A. Hidalgo
A virtual Schottky group is a Kleinian group containing a Schottky group as a finite index normal subgroup. These groups correspond to those groups of automorphisms of clos…
Zapponi-orientable dessins d'enfants
E. Girondo, G. González-Diez, R. A. Hidalgo +1
Almost two decades ago Zapponi introduced a notion of orientability of a clean dessin d'enfant, based on an orientation of the embedded bipartite graph. We extend this concept, whi…
