On the singular value decomposition of (skew-)involutory and (skew-)coninvolutory matrices

open access: yesSpecial Matrices, 2020
The singular values σ > 1 of an n × n involutory matrix A appear in pairs (σ, 1σ{1 \over \sigma }). Their left and right singular vectors are closely connected. The case of singular values σ = 1 is discussed in detail. These singular values may appear in

Fast singular value thresholding without singular value decomposition [PDF]

open access: yesMethods and Applications of Analysis, 2013
We are interested in solving the following minimization problem Dτ (Y ) := arg min X∈Rm×n 1 2 ∥Y −X∥F + τ∥X∥∗, where Y ∈ Rm×n is a given matrix, and ∥ ⋅ ∥F is the Frobenius norm and ∥ ⋅ ∥∗ the nuclear norm. This problem serves as a basic subroutine in many popular numerical schemes for nuclear norm minimization problems, which arise from low rank ...

On the N-spectrum of oriented graphs

open access: yesOpen Mathematics, 2020
Given any digraph D, its non-negative spectrum (or N-spectrum, shortly) consists of the eigenvalues of the matrix AA T, where A is the adjacency matrix of D.

Robust Parameter Estimation of an Empirical Manoeuvring Model Using Free-Running Model Tests

open access: yesJournal of Marine Science and Engineering, 2021
The work presents the identification and validation of the hydrodynamic coefficients for the surge, sway, and yaw motion. This is performed in two ways: using simulated data and free-running test data.

Singular Value Decomposition

open access: yesTheoretical and Natural Science
Singular Value Decomposition (SVD) is a very important matrix factorization technique in linear algebra which generalizes the eigenvalue decomposition to both non square and non symmetric matrices. This report explains the theoretical foundation of SVD by numerical examples and the comparison of SVD with eigenvalue decomposition on the basis of ...

Variational Quantum Singular Value Decomposition [PDF]

open access: yesQuantum, 2021
Singular value decomposition is central to many problems in engineering and scientific fields. Several quantum algorithms have been proposed to determine the singular values and their associated singular vectors of a given matrix.

The Singular Values of the GOE [PDF]

open access: yes, 2015
As a unifying framework for examining several properties that nominally involve eigenvalues, we present a particular structure of the singular values of the Gaussian orthogonal ensemble (GOE): the even-location singular values are distributed as the ...

The Stability Analysis of Linear Systems with Cauchy—Polynomial-Vandermonde Matrices

open access: yesAxioms, 2023
The numerical approximation of both eigenvalues and singular values corresponding to a class of totally positive Bernstein–Vandermonde matrices, Bernstein–Bezoutian structured matrices, Cauchy—polynomial-Vandermonde structured matrices, and quasi ...

Singularity, Wielandt’s lemma and singular values

open access: yesJournal of Computational and Applied Mathematics, 2010
The authors obtain some upper and lower bounds for the largest and the smallest singular values of certain complex matrices based on the entries and diagonal dominance. A relationship between largest singular value of a block matrix and its block norm matrix is obtained. Numerical examples are given to demonstrate the usefulness of their results.

The Smallest Singular Values and Vector-Valued Jack Polynomials [PDF]

open access: yes, 2018
There is a space of vector-valued nonsymmetric Jack polynomials associated with any irreducible representation of a symmetric group. Singular polynomials for the smallest singular values are constructed in terms of the Jack polynomials.
