二维亥姆霍兹算子中的准格林函数方法

Green Quasifunction Method in Two Dimensional Helmholtz Operator

应用准格林函数方法，将二维亥姆霍兹方程化为一个第二类Ｆｒｅｄｈｏｌｍ积分方程。通过边界方程的适当选择，积分方程核的奇异性被克服了。

Green quasifunction method is applied to two dimensional Helmholtz equation. A Fredholm integral equation of the second kind is obtained. lrregularity of the kernel of integral equation is overcome by choosing a suitable form of the normalized boundary equation.
