摘要
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 C-1,C-gamma. Our results apply to the classical Prandtl-Bachelor model in fluiddynamics. (C) 2015 Elsevier Ltd. All rights reserved.
