THE NATURAL BOUNDARY ELEMENT METHOD FOR EXTERIOR ELLIPTIC DOMAIN
椭圆外区域上的自然边界元法

In this paper we discuss the natural boundary element method for harmonic equation in an exterior elliptic domain. By studying the properties of the natural integral operator and the Poisson integral operator, we develop a numerical method to solve the natural integral equation. We also devise a fast algorithm for the solution of the corresponding system of linear equations. Finally we present some numerical results.
