On The Dirichlet Problem For Hessian Equations

Neil S. Trudinger

Abstract: We prove the solvability of the classical Dirichlet problem for Hessian equations determined by symmetric functions of the eigenvalues of the Hessian matrix of second derivatives. We extend the previous investigation of Caffarelli, Nirenberg and Spruck and others, through conditions embracing examples typified by quotients of elementary symmetric functions. We also provide a new proof of a crucial second derivative estimate in the cases previously considered, including the Monge-Ampère equations.
