Important Issues on Spectral Properties of a Transmission Eigenvalue Problem

International Journal of Differential Equations, 2021
Nowadays, inverse scattering is an important field of interest for many mathematicians who deal with partial differential equations theory, and the research in inverse scattering is in continuous progress. There are many problems related to scattering by

Determination of the Impulsive Dirac Systems from a Set of Eigenvalues

Mathematics, 2023
In this work, we consider the inverse spectral problem for the impulsive Dirac systems on (0,π) with the jump condition at the point π2. We conclude that the matrix potential Q(x) on the whole interval can be uniquely determined by a set of eigenvalues ...

Numerical construction of structured matrices with given eigenvalues

Special Matrices, 2019
We consider a structured inverse eigenvalue problem in which the eigenvalues of a real symmetric matrix are specified and selected entries may be constrained to take specific numerical values or to be nonzero.

Computation of interior elastic transmission eigenvalues using a conforming finite element and the secant method

Results in Applied Mathematics, 2020
The interior elastic transmission eigenvalue problem, arising from the inverse scattering theory of non-homogeneous elastic media, is nonlinear, non-self-adjoint and of fourth order.

Inverse multiparameter eigenvalue problems for matrices III [PDF]

Proceedings of the Edinburgh Mathematical Society, 1986
This note will complement and, in a certain sense, complete our earlier studies [3, 4] of the theory of inverse multiparameter eigenvalue problems for matrices. In those papers, we considered the so called “additive inverse problem” which, briefly stated for the 2-parameter case, asks for conditions on given n × n matrices A, B, C and on given points ...

Estimates of complex eigenvalues and an inverse spectral problem for the transmission eigenvalue problem

Electronic Journal of Qualitative Theory of Differential Equations, 2019
This work deals with the interior transmission eigenvalue problem: $y'' + {k^2}\eta \left( r \right)y = 0$ with boundary conditions ${y\left( 0 \right) = 0 = y'\left( 1 \right)\frac{{\sin k}}{k} - y\left( 1 \right)\cos k},$ where the function $\eta(r ...

Recursive integral method for transmission eigenvalues

, 2015
Recently, a new eigenvalue problem, called the transmission eigenvalue problem, has attracted many researchers. The problem arose in inverse scattering theory for inhomogeneous media and has important applications in a variety of inverse problems for ...
