Abstract

Let $M$ be an open Riemann surface and $n \geq 3$ be an integer. We prove that on any closed discrete subset of $M$ one can prescribe the values of a conformal minimal immersion $M \to ℝ^{n}$ . Our result also ensures jet-interpolation of given finite order, and hence, in particular, one may in addition prescribe the values of the generalized Gauss map. Furthermore, the interpolating immersions can be chosen to be complete, proper into $ℝ^{n}$ if the prescription of values is proper, and injective if $n \geq 5$ and the prescription of values is injective. We may also prescribe the flux map of the examples.

We also show analogous results for a large family of directed holomorphic immersions $M \to ℂ^{n}$ , including null curves.
