In this paper, we prove that every conformal minimal immersion of a compact bordered Riemann surface MM into a minimally convex domain DR3D\subset \mathbb{R}^3 can be approximated, uniformly on compacts in M˚=MbM\mathring M=M\setminus bM, by proper complete conformal minimal immersions M˚D\mathring M\to D. We also obtain a …

The ultimate goal of optimization is to find the minimizer of a target function.However, typical criteria for active optimization often ignore the uncertainty about the minimizer. We propose a novel criterion for global optimization and an associated sequential active learning strategy using Gaussian processes.Our crit…

A general study of minimal surfaces of the Riemannian product of two spheres S^2xS^2 is tackled. We stablish a local correspondence between (non-complex) minimal surfaces of S^2xS^2 and certain pair of minimal surfaces of the sphere S^3. This correspondence also allows us to link minimal surfaces in S^3 and in the Riem…

We prove that the Gauss curvature and the curvature of the normal connection of any minimal surface in the four dimensional Euclidean space satisfy an inequality, which generates two classes of minimal surfaces: minimal surfaces of general type and minimal super-conformal surfaces.
