Curvature estimates for the level sets of solutions of the Monge-Ampère equation $\det D^{2}u=1$

Abstract

For the Monge-Ampère equation $\det D^{2}u=1$, we find new auxiliary curvature functions which attain respective maximum on the boundary. Moreover, we obtain the upper bounded estimates for the Gauss curvature and mean curvature of the level sets for the solution to this equation.
