本文指出了用Rayleigh-Ritz投影技术的Sakurai-Sugiura方法是一种求解广义特征值问题的数值方法,它可以推广到非线性特征值问题。目标方程是T(λ)v = 0,其中T是矩阵值函数。该方法通过将原问题转化为一个维数较小的问题,只提取Jordan曲线Γ内的特征值。理论验证的方法进行了讨论,我们描述了它的应用程序使用数值例子。
In this paper, we indicate that the Sakurai-Sugiura method with Rayleigh-Ritz projection technique, a numerical method for generalized eigenvalue problems, can be extended to nonlinear eigenvalue problems. The target equation is T (λ)v = 0, where T is a matrix-valued function. The method can extract only the eigenvalues within a Jordan curve Γ by converting the original problem to a problem with a smaller dimension. Theoretical validation of the method is discussed, and we describe its application using numerical examples.
