Eigenvalue Problems for Fredholm Operators with Set-Valued Perturbations

Advanced 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.

Eigenvalues and Eigenvectors

, 1997
The decomposition of a matrix A into a product of two or three matrices can (depending on the characteristics of those matrices) be a very useful first step in computing such things as the rank, the determinant, or an (ordinary or generalized) inverse (of A) as well as a solution to a linear system having A as its coefficient matrix.

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

Acta 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.

Sensitivity Analysis of Eigenvalues for PDNT Toeplitz Matrices

Axioms
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,

Accuracy of genomic BLUP when considering a genomic relationship matrix based on the number of the largest eigenvalues: a simulation study

Genetics Selection Evolution, 2019
Background The dimensionality of genomic information is limited by the number of independent chromosome segments (M e ), which is a function of the effective population size.

Perfect state transfer in unitary Cayley graphs over local rings [PDF]

Transactions on Combinatorics, 2014
In this work, using eigenvalues and eigenvectors of unitary Cayley graphs over finite local rings and elementary linear algebra, we characterize which local rings allowing PST occurring in its unitary Cayley graph.

Eigenpairs of adjacency matrices of balanced signed graphs

Special Matrices
In this article, we study eigenvalues λ\lambda and their associated eigenvectors xx of the adjacency matrices AA of balanced signed graphs. Balanced signed graphs were first introduced and studied by Harary to handle a problem in social psychology ...
