摘要: 位势方程是偏微分方程理论研究中的一类典型的二阶椭圆型方程。对位势方程的Robin问题作了深入研究,运用散度定理证明了该问题在C1-)?C2(Ω)中解的唯一性,并运用Green函数法导出该问题的Green函数G(x,y)满足的条件和该问题的解的表达式。

关键词: 位势方程, Robin 问题, Green 函数, 椭圆型方程

Abstract: The potential equation is a typical second-order elliptic equation in the theoretical research of partial differential equations. In this paper,the Robin problem of the potential equation was studied deeply. We proved the uniqueness of its solution in C1-)?C2(Ω)by the divergence theorem. The conditions satisfied by the Green's function G(x,y)and the expression of its solution were derived by Green's function method.

Key words: potential equation, Robin problem, Green's function, elliptic equation
