Boundary Regularity for the Free Boundary in the One-phase Problem

Analysis of PDEs 2017-09-12 v1

Abstract

We consider the Bernoulli one-phase free boundary problem in a domain Ω\Omega and show that the free boundary FF is C1,1/2C^{1,1/2} regular in a neighborhood of the fixed boundary Ω\partial \Omega. We achieve this by relating the behavior of FF near Ω\partial \Omega to a Signorini-type obstacle problem.
