Minimal immersions of compact bordered Riemann surfaces with free boundary
TLDR
In this article, it was shown that for any continuous Riemannian manifold f: (\Sigma, \partial \Sigma) \rightarrow (N, M)$ for which the induced homomorphism on certain fundamental groups is injective, there exists a branched minimal immersion of f solving the free boundary problem.Abstract:
Let N be a complete, homogeneously regular Riemannian manifold of dimension greater than 2 and let M be a compact submanifold of N. Let $\Sigma$ be a compact orientable surface with boundary. We show that for any continuous $f: (\Sigma, \partial \Sigma) \rightarrow (N, M)$ for which the induced homomorphism on certain fundamental groups is injective, there exists a branched minimal immersion of $\Sigma$ solving the free boundary problem $(\Sigma, \partial \Sigma) \rightarrow (N, M)$, and minimizing area among all maps which induce the same action on the fundamental groups as f. Furthermore, under certain nonnegativity assumptions on the curvature of a 3-manifold N and convexity assumptions on M which is the boundary of N, we derive bounds on the genus, number of boundary components and area of any compact two-sided minimal surface solving the free boundary problem with low index.read more

Index estimates for free boundary minimal hypersurfaces
TL;DR: In this paper, it was shown that the Morse index of a properly embedded free boundary minimal hypersurface in a strictly mean convex domain of the Euclidean space grows linearly with the dimension of its first relative homology group (which is at least as big as the number of its boundary components, minus one).

TL;DR: The conformal volume of a compact Riemannian manifold with a fixed conformal structure was defined in this article, where it was shown that the conformal area of a manifold can be computed by the set of all branched conformal immersions obtained by composi t ion of qo with conformal automorphisms of S. In fact, if there exists a minimal immersion of M into S, where coordinate functions are first eigenfunctions, then the conformality of M is given by the area of M with respect to the induced metric.
