Abstract

Let MM be an open Riemann surface and n3n\ge 3 be an integer. In this paper we establish some generic properties (in Baire category sense) in the space of all conformal minimal immersions MRnM\to\mathbb{R}^n endowed with the compact-open topology, pointing out that a generic such immersion is chaotic in many ways. For instance, we show that a generic conformal minimal immersion u ⁣:MRnu\colon M\to \mathbb{R}^n is non-proper, almost proper, and gg-complete with respect to any given Riemannian metric gg in Rn\mathbb{R}^n. Further, its image u(M)u(M) is dense in Rn\mathbb{R}^n and disjoint from Q3×Rn3\mathbb{Q}^3\times \mathbb{R}^{n-3}, and has infinite area, infinite total curvature, and unbounded curvature on every open set in Rn\mathbb{R}^n. In case n=3n=3, we also prove that a generic conformal minimal immersion MR3M\to\mathbb{R}^3 has infinite index of stability on every open set in R3\mathbb{R}^3.
