WebMar 25, 2016 · One version of the uniformization theorem says that a simply connected complex manifold of (complex) dimension one is biholomorphic to either the unit disc, C, or C P 1. The proof of this goes through potential theory, ultimately using analysis of subharmonic functions to obtain a biholomorphic map to an open subset of C P 1.
