Quasisymmetric Koebe Uniformization of metric surfaces
Abstract
We study when a metric surface can be mapped quasisymmetrically onto a circle domain with uniformly relatively separated boundary components. Bonk \cite{Bonk} proved that if and the boundary components of are uniformly relatively separated uniform quasicircles then is quasisymmetric to a circle domain. Merenkov and Wildrick \cite{Merenkov Wildrick} showed that Bonk's condition is not sufficient in the non-planar case. We prove that under some mild assumptions, a metric surface is quasisymmetric to a circle domain with uniformly relatively separated boundary components if and only if it is 2-TLP. The latter is a version of a condition introduced and studied by Bonk \cite{Bonk}. This answers a question of Merenkov and Wildrick in \cite{Merenkov Wildrick} and it is also a natural generalization of Bonk's result to non-planar metric surfaces.
