Regularity of solutions to fully nonlinear elliptic and parabolic free boundary problems

Emanuel Indrei, Andreas Minne

We consider fully nonlinear obstacle-type problems of the form \begin{equation*} \begin{cases} F(D^{2}u,x)=f(x) & \text{a.e. in}B_{1}\capΩ,|D^{2}u|\le K & \text{a.e. in}B_{1}\backs…
