Abstract:

This paper is dedicated to studying the optimal global estimates and nonexistence of strictly convex solutions to the boundary blow-up Monge-Ampère problem M[u](x)=K(x)f(u) for xΩ,u(x)+ as dist(x,Ω)0. Here M[u]=det(uxixj) is the Monge-Ampère operator, and Ω denotes a smooth, bounded, strictly convex domain in RN(N2). The interesting features in our proof are that we not only obtain the relations among various conditions imposed on K(x) and f(u), but make comparison of some results of global estimates in previous literatures and make clear what conditions lead to what estimations. Moreover, when Ω is a general region, we give some nonexistence results which is rarely discussed in previous literatures.

Key words: Monge-Ampère equation, Boundary blow-up, Global estimates, Strictly convex solution, Nonexistence
