Cyclic-Schottky strata of Schottky space

Ruben A. Hidalgo, Milagros Izquierdo

Schottky space $S_{g}$ , where $g \geq 2$ is an integer, is a connected complex orbifold of dimension $3 (g - 1)$ ; 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 $S$ 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 $K$ containing a Schottky group $G$ as a finite index normal subgroup. These groups correspond to those groups of automorphisms of clos…
