摘要
For the fully nonlinear uniformly elliptic equation F(D (2) u) = 0, it is well known that the viscosity solutions are C (2,alpha) if the nonlinear operator F is convex (or concave). In this paper, we study the classical solutions for the fully nonlinear elliptic equation where the nonlinear operator F is locally C (1,beta) a.e. for any 0 < beta < 1. We will prove that the classical solutions u are C (2,alpha) . Moreover, the C (2,alpha) norm of u depends on n, F and the continuous modulus of D (2) u.
