Minimal surfaces in minimally convex domains

In this paper, we prove that every conformal minimal immersion of a compact bordered Riemann surface M into a minimally convex domain D\subset \mathbb{R}^3 can be approximated uniformly on compacts in \mathring M=M\setminus bM by proper complete conformal minimal immersions \mathring M\to D. We also...

Description
Summary:In this paper, we prove that every conformal minimal immersion of a compact bordered Riemann surface M into a minimally convex domain D\subset \mathbb{R}^3 can be approximated uniformly on compacts in \mathring M=M\setminus bM by proper complete conformal minimal immersions \mathring M\to D. We also obtain a rigidity theorem for complete immersed minimal surfaces of finite total curvature contained in a minimally convex domain in \mathbb{R}^3, and we characterize the minimal surface hull of a compact set K in \mathbb{R}^n for any n\ge 3 by sequences of conformal minimal discs whose boundaries converge to K in the measure theoretic sense.
