Local Solvability of Degenerate Monge-ampère Equations and Applications to Geometry

چکیده

We consider two natural problems arising in geometry which are equivalent to the local solvability of specific equations of Monge-Ampère type. These are: the problem of locally prescribed Gaussian curvature for surfaces in R3, and the local isometric embedding problem for two-dimensional Riemannian manifolds. We prove a general local existence result for a large class of degenerate Monge-Ampère equations in the plane, and obtain as corollaries the existence of regular solutions to both problems, in the case that the Gaussian curvature vanishes and possesses a nonvanishing Hessian matrix at a critical point.

On Degenerate Monge-Ampère Equations over Closed Kähler Manifolds

Monge-Ampère equation has been a classic problem in analysis for a long time. Its complex version, complex Monge-Ampère equation, has drawn a lot of intentions from an even wider group of mathematicians since the breakthrough work of S. -T. Yau almost thirty years ago. The solvability of this equation over a closed manifold for a Kähler class, which was proved in [Ya], allows a lot of applicati...

The Dirichlet Problem for Monge-ampère Equations in Non-convex Domains and Spacelike Hypersurfaces of Constant Gauss Curvature

In this paper we extend the well known results on the existence and regularity of solutions of the Dirichlet problem for Monge-Ampère equations in a strictly convex domain to an arbitrary smooth bounded domain in Rn as well as in a general Riemannian manifold. We prove for the nondegenerate case that a sufficient (and necessary) condition for the classical solvability is the existence of a subs...

Schauder estimates for degenerate Monge–Ampère equations and smoothness of the eigenfunctions

We obtainC2,β estimates up to the boundary for solutions to degenerate Monge–Ampère equations of the type det D2u = f in , f ∼ distα(·, ∂ ) near ∂ , α > 0. As a consequence we obtain global C∞ estimates up to the boundary for the eigenfunctions of the Monge–Ampère operator (det D2u)1/n on smooth, bounded, uniformly convex domains in Rn .
