Abstract

We establish a correspondence on a Riemann surface between hyperbolic metrics with isolated singularities and bounded projective functions whose Schwarzian derivatives have at most double poles and whose monodromies lie in PSU(1,1){\rm PSU}(1,\,1). As an application, we construct explicitly a new class of hyperbolic metrics with countably many singularities on the unit disc.

Comments

14 pages. We revised the old version greatly. In particular, we changed the title a little bit, generalized the main theorem to general Riemann surface, added a complex analytical definition for cone/cusp singularity of hyperbolic metric and Example 1.1
