Almost minimizers of the one-phase free boundary problem
Daniela De Silva, Ovidiu Savin
We consider almost minimizers to the one-phase energy functional and we prove their optimal Lipschitz regularity and partial regularity of their free boundary. These results were r…

Free boundary regularity for fully nonlinear non-homogeneous two-phase problems
D. De Silva, F. Ferrari, S. Salsa
We prove that flat or Lipschitz free boundaries of two-phase free boundary problems governed by fully nonlinear uniformly elliptic operators and with non-zero right hand side are $…
