Abstract

We study entire continuous viscosity solutions to fully nonlinear elliptic equations involving the conformal Hessian. We prove the strong comparison principle and Hopf Lemma for (non-uniformly) elliptic equations when one of the competitors is C1,1C^{1,1}. We obtain as a consequence a Liouville theorem for entire solutions which are approximable by C1,1C^{1,1} solutions on larger and larger compact domains, and, in particular, for entire Cloc1,1C^{1,1}_{\rm loc} solutions: they are either constants or standard bubbles.
