摘要
本文考虑两区间上三阶微分方程的特征值关于各个参数的依赖性问题.将边界条件分为四点全部分离以及两点分别耦合两种情况,给出问题的特征值关于系数函数以及这两类边界条件的各个参数的连续性以及微分表达式.
In this paper, the dependence of eigenvalues of two-interval third-order differential boundary value problems on various parameters is investigated. Under two types of special boundary conditions, the continuity and differentiability of eigenvalues on the problems are shown, especially the differential expressions with respect to each coefficient functions and boundary conditions are given.
