传输问题的一种新的级数解方法

A new series solution method for the transmission problem

YoungHoon Jung, Mikyoung Lim

摘要:

利用一般形状域的外共形映射,导出了Neumann-Poincare算子的解析级数表示.我们利用Faber多项式基对任意Lipschitz域导出了该公式。利用所提出的方法,我们可以通过求矩阵的特征值来逼近光滑区域的谱。我们还明确地找到了边界积分方程与外共形映射之间的联系。

英文摘要:

We derive analytic series representation for the Neumann-Poincare operator using the exterior conformal mapping for general shape domains. We derive the formula by using the Faber polynomial basis for arbitrary Lipschitz domains. With the proposed method we can approximate the spectrum of the smooth domains by finding the eigenvalues of matrices. We also find the connection of the boundary integral equations with the exterior conformal mapping, explicitly.
