内禀圆域

Intrinsic circle domains

Edward Crane

摘要:

利用拟共形映射,证明了任意有限连通有限亏格的Riemann曲面共形等价于紧致Riemann曲面S中的内禀圆域U。这意味着S \ U的每个连通分量B要么是一个点,要么是一个关于黎曼曲面的完全常曲率共形度量(U并集B)的封闭几何圆盘。此外,对(U,S)是唯一的共形同构。给出了可数无限连通性的一个推广。最后,我们将展示如何计算数值逼近内圆域使用圆包装和保形焊接。

英文摘要:

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.
