将文献[1]中的方法运用到一类Monge-Ampère方程det[D^2u-σ(x,u)]=f(x,u,Du)的Neumann边值问题中,分别得到梯度内估计,近边梯度估计以及边界梯度估计,从而得到退化椭圆解的全局梯度估计.
We extend the method in [1]to general Monge-Ampère equations det[D^2u- σ( x,u) ]= f( x,u,Du) with the Neumann boundary value condition,and get the interior gradient estimates,near the boundary gradient estimates and boundary gradient estimates respectively,then we obtain global gradient estimates of the degenerate elliptic solution.
