The Stability of Embedded Eigenvalues for operator

ISBN: 9786138924241 出版年：2020 页码：52 Nifeen Altaweel Scholars' Press

This article focuses on the perturbation problem for operators; this problem is considered one of the partial differential equations; a possible example of this problem is the embedded eigenvalues, and it serves as a prototype of this problem. The perturbation problems for operators with embedded eigenvalues are generally challenging since the embedded eigenvalues can not be separated from the rest of the spectrum.
