Boundary rigidity of Gromov hyperbolic spaces
Hao Liang, Qingshan Zhou
We introduce the concept of boundary rigidity for Gromov hyperbolic spaces. We show that a proper geodesic Gromov hyperbolic space with a pole is boundary rigid if and only if its…
Gromov hyperbolicity in the free quasiworld. I
Qingshan Zhou, Saminathan Ponnusamy
With the aid of a Gromov hyperbolic characterization of uniform domains, we first give an affirmative answer to an open question arisen by Väisälä under weaker assumption. Next, we…
A note on -bilipschitz mappings in quasiconvex metric spaces
Tiantian Guan, Saminathan Ponnusamy, Qingshan Zhou
This paper focuses on properties of \partial-biLipschitz mappings which were recently introduced by Bulter. We establish several characterizations for the class of \partial-biLipsc…
Some remarks on the Gehring-Hayman theorem
Sari Rogovin, Hyogo Shibahara, Qingshan Zhou
In this paper we provide new characterizations of the Gehring-Hayman theorem from the point of view of Gromov boundary and uniformity. We also determine the critical exponents for…
