Abstract
For any open orientable surface M and convex domain \({\Omega\subset \mathbb{C}^3,}\) there exist a Riemann surface N homeomorphic to M and a complete proper null curve F : N → Ω. This result follows from a general existence theorem with many applications. Among them, the followings:
-
For any convex domain Ω in \({\mathbb{C}^2}\) there exist a Riemann surface N homeomorphic to M and a complete proper holomorphic immersion F : N → Ω. Furthermore, if \({D \subset \mathbb{R}^2}\) is a convex domain and Ω is the solid right cylinder \({\{x \in \mathbb{C}^2 \,|\, \mbox{Re}(x) \in D\},}\) then F can be chosen so that Re(F) : N → D is proper.
-
There exist a Riemann surface N homeomorphic to M and a complete bounded holomorphic null immersion \({F:N \to {\rm SL}(2, \mathbb{C}).}\)
-
There exists a complete bounded CMC-1 immersion \({X:M \to \mathbb{H}^3.}\)
-
For any convex domain \({\Omega \subset \mathbb{R}^3}\) there exists a complete proper minimal immersion (X j ) j=1,2,3 : M → Ω with vanishing flux. Furthermore, if \({D \subset \mathbb{R}^2}\) is a convex domain and \({\Omega=\{(x_j)_{j=1,2,3} \in \mathbb{R}^3 \,|\, (x_1,x_2) \in D\},}\) then X can be chosen so that (X 1, X 2) : M → D is proper.
Any of the above surfaces can be chosen with hyperbolic conformal structure.
