摘要：

We prove Runge-type theorems and universality results for locally univalent holomorphic and meromorphic functions. Refining a result of M.Heins, we also show that there is a universal bounded locally univalent function on the unit disk. These results are used to prove that on any hyperbolic simply connected plane domain there exist universal conformal metrics with prescribed constant curvature.
