On the exterior Dirichlet problem for Hessian type fully nonlinear elliptic equations

Abstract

We treat the exterior Dirichlet problem for a class of fully nonlinear elliptic equations of the form $$f(\lambda (D^{2}u))=g(x),$$ with prescribed asymptotic behavior at infinity. The equations of this type had been studied extensively by Caffarelli--Nirenberg--Spruck \cite{Caffarelli1985}, Trudinger \cite{Trudinger1995} and many others, and there had been significant discussions on the solvability of the classical Dirichlet problem via the continuity method, under the assumption that $f$ is a concave function. In this paper, based on the Perron's method, we establish an exterior existence and uniqueness result for viscosity solutions of the equations by assuming $f$ to satisfy certain structure conditions as in \cite{Caffarelli1985,Trudinger1995}, which may embrace the well-known Monge--Ampère equations, Hessian equations and Hessian quotient equations as special cases but do not require the concavity.
