The Diagonalizable Nonnegative Inverse Eigenvalue Problem

open access: yesSpecial Matrices, 2018
In this articlewe provide some lists of real numberswhich can be realized as the spectra of nonnegative diagonalizable matrices but which are not the spectra of nonnegative symmetric matrices.

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

open access: yesElectronic 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 ...

Some notes on conformable fractional Sturm–Liouville problems

open access: yesBoundary Value Problems, 2021
The conformable fractional eigenvalue problem − D x α D x α y + q ( x ) y = λ ρ ( x ) y $$\begin{aligned} -D_{x}^{\alpha }D_{x}^{\alpha }y+q(x)y=\lambda \rho (x)y \end{aligned}$$ is considered.

A linear eigenvalue algorithm for the nonlinear eigenvalue problem [PDF]

open access: yesNumerische Mathematik, 2012
A nonlinear matrix eigenvalue problem (NMEP) \(T(\lambda)x=0\) is transformed without loss of generality into a standard form \(\lambda B(\lambda)x=x\) (\(T\) and \(B\) analytic in \(\Omega\subset\mathbb{C}\)). This is then transformed into a linear operator eigenvalue problem (LOEP) of the form \(\lambda\mathcal{B}\varphi=\varphi\) (\(\varphi\in C_ ...

Solving Overdetermined Eigenvalue Problems [PDF]

open access: yesSIAM Journal on Scientific Computing, 2013
We propose a new interpretation of the generalized overdetermined eigenvalue problem $\left({\bf A} - \lambda {\bf B}\right){\bf v} \approx 0$ for two $m\times n$ ($m > n$) matrices ${\bf A}$ and ${\bf B}$, its stability analysis, and an efficient algorithm for solving it.
