摘要 本文讨论反射天线面设计中出现的一个偏微分方程,这是一个完全非线性Monge-Ampère型方程.我们先给出一个广义解的定义,然后介绍如何得到广义解的存在性、唯一性和正则性,最后我们给出求数值解的一个方法. In this paper, we discuss a partial differential equation arising in the design of a reflector antenna. It is a fully nonlinear equation of Monge-Ampère type. We first introduce a generalized solution, then consider the existence, uniqueness and regularity of generalized solutions. Finally, we present an approach to its numerical solution.
