In this paper we study the free boundary regularity for almost-minimizers of the functional J (u)=∫ Ω|∇ u (x)| 2+ q+ 2 (x) χ {u> 0}(x)+ q− 2 (x) χ {u< 0}(x) d x where q±∈ L∞(Ω). Almost-minimizers satisfy a variational inequality but not a PDE or a monotonicity formula the way minimizers do (see [4],[5],[9],[37]). Nevertheless, using a novel argument which brings together tools from potential theory and geometric measure theory, we succeed in proving that, under a non-degeneracy assumption on q±, the free boundary is uniformly rectifiable. Furthermore, when q−≡ 0, and q+ is Hölder continuous we show that the free boundary is almost-everywhere given as the graph of a C 1, α function (thus extending the results of [4] to almost-minimizers).
