Abstract

In this paper we first introduced a domain called generalized Dirichlet fundamental domain F\mathcal{F}^{*} for a Fuchsian group GG whose generators contain parabolic elements. This allows us to show that a quasisymmetric homeomorphism hh being compatible with a convergence Fuchsian group GG of first kind is a strongly quasisymmetric homeomorphism if and only if it has a quasiconformal extension ff to the upper half plane H\mathbb{H} onto itself such that the induced measure λμ=μ2/Im(z)dxdy\lambda_{\mu}=|\mu|^{2}/Im(z)dxdy by the Beltrami coefficient μ\mu of ff is a Carleson measure on the generalized Dirichlet fundamental domain F.\mathcal{F}^{*}. We also show that the above property also holds for Carleson-Denjoy domains.
