Viscosity solutions of the augmented k-Hessian equations in exterior domains

This paper examines the Dirichlet problem for augmented k-Hessian equations in exterior domains. Building upon our previous results on the viscosity solutions to the Dirichlet problems for augmented k -Hessian equations in the bounded domain, and L. Dai, J. Bao's method to the k-Hessian equations in exterior domains, a sufficient condition for the existence and uniqueness of viscosity solutions to the Dirichlet problem for the augmented k-Hessian equations in exterior domains have been proven.
