Regularity of Free Boundary Minimal Surfaces in Locally Polyhedral Bomains
Chao Li (New York University, Courant Institute)
We prove an Allard-type regularity theorem for free- boundary minimal surfaces in Lipschitz domains locally modelled on convex polyhedra. We show that if such a minimal surface is sufficiently close to an appropriate free-boundary plane, then the surface is graphical over this plane. We apply our theorem to prove partial regularity results for free-boundary minimizing hypersurfaces, and isoperimetric regions. This is based on a joint work with Nick Edelen.
