讨论二阶非线性椭圆型方程的斜微商边值问题。首先给出这种边值问题解的表示式和估计式,进而证明上述问题解的存在唯一性。
This paper deals with the oblique derivative boundary value problem for nonlinear elliptic equations of second order. First, the representation and a priori estimates of solutions for the above boundary value problem were given, and then the uniqueness and existence of solutions of the above problem for the second order equations was proved.
