    Intrinsic circle domains


    Crane, ET, 2014, ‘Intrinsic circle domains’. Conformal Geometry and Dynamics, vol 18., pp. 65-84


    Using quasiconformal mappings, we prove that any Riemann surface of finite connectivity and finite genus is conformally equivalent to an intrinsic circle domain U in a compact Riemann surface S. This means that each connected component B of S\U is either a point or a closed geometric disc with respect to the complete constant curvature conformal metric of the Riemann surface U union B. Moreover, the pair (U, S) is unique up to conformal isomorphisms. We give a generalization to countably infinite connectivity. Finally, we show how one can compute numerical approximations to intrinsic circle domains using circle packings and conformal welding.
