Abstract:
Let $G\subsetneq \mathbb {R}^n$ be an open set. It is shown by Hästö that $G$ equipped with the $\tilde {j}_G$ metric is Gromov hyperbolic. The purpose of this paper is to show that there is a natural quasisymmetric correspondence between the Gromov boundary of $(G, \tilde {j}_G)$ and its Euclidean boundary $\partial G$. Both bounded and unbounded cases are in our considerations.References
