摘要

我们导出了拉普拉斯方程在三维欧氏空间的平环坐标系中的基本解的展开式。这个扩展是“平面环”内部和外部和谐的功能的双系列产品。这些内部和外部平环调和函数用简单的周期Lamé函数表示。在极限情况下,我们得到了基本解在环面坐标系中的展开式。

Expansion for a Fundamental Solution of Laplace's Equation in Flat-Ring Cyclide Coordinates
We derive an expansion for the fundamental solution of Laplace's equation in flat-ring coordinates in three-dimensional Euclidean space. This expansion is a double series of products of functions that are harmonic in the interior and exterior of ''flat rings''. These internal and external flat-ring harmonic functions are expressed in terms of simply-periodic Lamé functions. In a limiting case we obtain the expansion of the fundamental solution in toroidal coordinates.
