Algebraic Bethe ansatz for the Temperley–Lieb spin-1 chain

open access: yesNuclear Physics B, 2016
We use the algebraic Bethe ansatz to obtain the eigenvalues and eigenvectors of the spin-1 Temperley–Lieb open quantum chain with “free” boundary conditions.

Eigenvalue Problems for Fredholm Operators with Set-Valued Perturbations

open access: yesAdvanced Nonlinear Studies, 2020
By means of a suitable degree theory, we prove persistence of eigenvalues and eigenvectors for set-valued perturbations of a Fredholm linear operator.

Complex modal analysis of structural vibration and acoustic radiation of plates

open access: yesJournal of Low Frequency Noise, Vibration and Active Control
Inhomogeneous damping distribution leads to the occurrence of complex modes of structures. Complex modes' vibration and acoustic radiation characteristics are different from real modes.

Partial eigenvalue assignment problem of linear control systems using orthogonality relations [PDF]

open access: yesActa Montanistica Slovaca, 2006
The partial eigenvalue assignment is the problem of reassigning a part of the open-loop spectrum of a linear system by a feedback control, leaving the rest of the spectrum invariant.

The affine equivariant sign covariance matrix: asymptotic behavior and efficiencies. [PDF]

open access: yes
We consider the affine equivariant sign covariance matrix (SCM) introduced by Visuri et al. (J. Statist. Plann. Inference 91 (2000) 557). The population SCM is shown to be proportional to the inverse of the regular covariance matrix. The eigenvectors and

Sensitivity Analysis of Eigenvalues for PDNT Toeplitz Matrices

open access: yesAxioms
This study focuses on a class of perturbed Dirichlet–Neumann tridiagonal (PDNT) Toeplitz matrices, mainly exploring their eigenvalue sensitivity and inverse problems. By the explicit expressions for eigenvalues and eigenvectors of PDNT Toeplitz matrices,
