Removable singularities for fully nonlinear elliptic equations
Nonlinear uniformly elliptic equations with the fully nonlinearity with respect to second derivatives are considered. It is proved that the singularities in the solutions are removable under certain sharp conditions. The main result consists in the proof of the existence of removable isolated singularities. The viscosity notion is used in this connection.
