Regularity of the free boundary for two-phase problems governed by divergence form equations and applications

Analysis of PDEs 2017-02-27 v1

Abstract

We study a class of two-phase inhomogeneous free boundary problems governed by elliptic equations in divergence form. In particular we prove that Lipschitz or flat free boundaries are C1,γC^{1,\gamma}. Our results apply to the classical Prandtl-Bachelor model in fluiddynamics.
