a connected, closed and smooth Riemannian manifold. The functions H (x, p) and λ (x) are
continuous. H (x, p) is convex, coercive with respect to p, and λ (x) changes the signs. The
first breakthrough to this model was achieved by Jin-Yan-Zhao [11] under the Tonelli
conditions. In this paper, we consider more detailed structure of the viscosity solution set and
large time behavior of the viscosity solution on the Cauchy problem. To the best of our …
