Viscosity solutions of nonvariational elliptic equations
We discuss basic properties (uniqueness and regularity) of viscosity solutions to fully nonlinear elliptic equations of the form $F(x,D^2u)=0$, which includes also linear elliptic equations of nondivergent form. In the linear case we consider equations with discontinuous coefficients.
