Carleman approximation by conformal minimal immersions and directed holomorphic curves

Abstract

Let $\mathcal{R}$ be an open Riemann surface. In this paper we prove that every continuous function $M\to {\mathbb{R}}^n$, $n\ge 3$, defined on a divergent Jordan arc $M\subset \mathcal{R}$ can be approximated in the Carleman sense by conformal minimal immersions; thus providing a new generalization of Carleman's theorem. In fact, we prove that this result remains true for null curves and many other classes of directed holomorphic immersions for which the directing variety satisfies a certain flexibility property. Furthermore, the constructed immersions may be chosen to be complete or proper under natural assumptions on the variety and the continuous map. As a consequence we give an approximate solution to a Plateau problem for divergent Jordan curves in the Euclidean spaces.
