摘要:

基于泛函离散技术(FD-方法),开发了一种用于间断通量和可积势的特征值传输问题的算法。研究了势函数属于函数空间 $L_1$ 的情况,包括线性和非线性特征值问题。获得了保证方法超指数收敛速度的充分条件。给出了数值例子以支持理论。基于数值例子和收敛结果,得出了关于非自伴微分算子特征解解析性质的结论。

英文摘要:

Based on the functional-discrete technique (FD-method), an algorithm for eigenvalue transmission problems with discontinuous flux and integrable potential is developed. The case of the potential as a function belonging to the functional space $L_1$ is studied for both linear and nonlinear eigenvalue problems. The sufficient conditions providing superexponential convergence rate of the method were obtained. Numerical examples are presented to support the theory. Based on the numerical examples and the convergence results, conclusion about analytical properties of eigensolutions for nonself-adjoint differential operators is made.
