Topological Characterizations of Geometrically Infinite Convergence Group Actions and Orbit Uniform Metrics
Chaodong Yang
Two characterizations of geometric finiteness in terms of weaker conditions are known for actions on Gromov hyperbolic spaces. In this paper, we establish analogous characterizatio…

Two Characterizations of Geometrically Infinite Actions on Gromov Hyperbolic Spaces
Chaodong Yang, Wenyuan Yang
We provide two new characterizations of geometrically infinite actions on Gromov hyperbolic spaces: one in terms of the existence of escaping geodesics, and the other via the prese…
