This article presents some qualitative results for solutions of the fully nonlinear elliptic equation F(∇u,D2 u) + f(u) = 0 in RN. Precisely un- der some assumptions on f, if −1 &le u &le 1 and it converges to + and - 1 at infinity, uniformly with respect to x′, then the solution depends only on x1
