    A study on gradient blow up for viscosity solutions of fully nonlinear, uniformly elliptic equations
    (Oberwolfach : Mathematisches Forschungsinstitut Oberwolfach, 2009) Kawohl, Bernd; Kutev, Nikolai
    We investigate sharp conditions for boundary and interior gradient es- timates of continuous viscosity solutions to fully nonlinear, uniformly ellip- tic equations under Dirichlet boundary conditions. When these conditions are violated, there can be blow up of the gradient in the interior or on the boundary of the domain.
