Abstract

We use separation of variables to find the eigenvalues and the corresponding eigenfunctions of the Gellerstedt–Frankl boundary value problem (with deviation from the characteristics) for a mixed-type Lavrent’ev–Bitsadze equation in a special domain.

混合型Lavrent'ev-Bitsadze方程的光谱Gellerstedt-Frankl问题

摘要

我们使用变量的分离来找到特殊领域中混合型Lavrent'ev-Bitsadze方程的Gellerstedt-Frankl边值问题的特征值和相应的特征函数（与特征有所偏差）。
