C^{2,\alpha}$ regularity of flat free boundaries for the thin one-phase problem

Analysis of PDEs 2011-11-11 v1

Abstract

We prove C2,αC^{2,\alpha} regularity of sufficiently flat free boundaries, for the thin one-phase problem in which the free boundary occurs on a lower dimensional subspace. This problem appears also as a model of a one-phase free boundary problem in the context of the fractional Laplacian (Δ)1/2(-\Delta)^{1/2}.
