| Abstract | We establish an extension of Liouville's classical representation theorem for solutions of the partial differential equation (PDE) Δ u=4 e2u and combine this result with methods from nonlinear elliptic PDE to construct holomorphic maps with prescribed critical points and specified boundary behaviour. For instance, we show that for every Blaschke sequence {zj} in the unit disk there is always a Blaschke product with {zj} as its set of critical points. Our work is closely related to the Berger--Nirenberg problem in differential geometry. |
