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…

Conformal dynamics at infinity for groups with contracting elements
Wenyuan Yang
This paper develops a theory of conformal density at infinity for groups with contracting elements. We start by introducing a class of convergence boundary encompassing many known…

Uniform exponential growth for groups with proper product actions on hyperbolic spaces
Renxing Wan, Wenyuan Yang
This paper studies the locally uniform exponential growth and product set growth for a finitely generated group acting properly on a finite product of hyperbolic spaces. Under…
