| 英文摘要 | We study the boundary Value problems for Monge-Ampere equations: det D(2)u = e(-u) in Omega subset of R(n), n >= 1, u vertical bar(partial derivative Omega) = 0. First we prove that any solution on the ball is radially symmetric by the argument of moving plane. Then we show there exists a critical radius such that if the radius of a ball is smaller than this critical value there exists a Solution, and vice versa. Using the comparison between domains we can prove that this phenomenon occurs for every domain. Finally we consider an equivalent problem with a parameter det D(2)u = e(-tu) in Omega, u vertical bar(partial derivative Omega) = 0, t >= 0 . By using Lyapunov-Schmidt reduction method we get the local structure of the solutions near a degenerate point: by Leray-Schauder degree theory, a priori estimate and bifurcation theory we get the global structure.
