Harald Schmid

摘要:

本文研究了角向球波动方程及其推广的库仑球波动方程的特征值。一个相关的微分系统和公式之间的各种Floquet解决方案的连接系数产生一个完整的功能,其零点正是特征值的库仑椭球波方程。整个函数可以通过递推公式计算,具有任意精度和较低的计算成本。最后,得到了一个简单易用的方法来计算球的特征值和相应的特征函数。

英文摘要:

In this paper we study the eigenvalues of the angular spheroidal wave equation and its generalization, the Coulomb spheroidal wave equation. An associated differential system and a formula for the connection coefficients between the various Floquet solutions give rise to an entire function whose zeros are exactly the eigenvalues of the Coulomb spheroidal wave equation. This entire function can be calculated by means of a recurrence formula with arbitrary accuracy and low computational cost. Finally, one obtains an easy-to-use method for computing spheroidal eigenvalues and the corresponding eigenfunctions.
