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 singular values of the GOE

open access: yesRandom Matrices: Theory and Applications, 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 positive eigenvalues of a Gaussian ensemble with chiral unitary symmetry, while the odd-location ...

Bound for the largest singular value of nonnegative rectangular tensors

open access: yesOpen Mathematics, 2016
In this paper, we give a new bound for the largest singular value of nonnegative rectangular tensors when m = n, which is tighter than the bound provided by Yang and Yang in “Singular values of nonnegative rectangular tensors”, Front. Math.

An S-type singular value inclusion set for rectangular tensors

open access: yesJournal of Inequalities and Applications, 2017
An S-type singular value inclusion set for rectangular tensors is given. Based on the set, new upper and lower bounds for the largest singular value of nonnegative rectangular tensors are obtained and proved to be sharper than some existing results ...

Schur Complement-Based Infinity Norm Bounds for the Inverse of GDSDD Matrices

open access: yesMathematics, 2022
Based on the Schur complement, some upper bounds for the infinity norm of the inverse of generalized doubly strictly diagonally dominant matrices are obtained. In addition, it is shown that the new bound improves the previous bounds.

A basis of common approach to the development of universal steganalysis methods for digital images

open access: yesTrudy Odesskogo Politehničeskogo Universiteta, 2014
In this paper a new common approach to the organization of steganalysis in digital images is developed. New features of formal parameters defining the image are identified, theoretically grounded and practically tested. For the first time characteristics

New inclusion sets for singular values

open access: yesJournal of Inequalities and Applications, 2017
In this paper, for a given matrix A = ( a i j ) ∈ C n × n $A=(a_{ij}) \in\mathbb{C}^{n\times n}$ , in terms of r i $r_{i}$ and c i $c_{i}$ , where r i = ∑ j = 1 , j ≠ i n | a i j | $r_{i} = \sum _{j = 1,j \ne i}^{n} {\vert {a_{ij} } \vert }$ , c i = ∑ j =

On a Matrix Inequality Related to the Distillability Problem

open access: yesEntropy, 2018
We investigate the distillability problem in quantum information in ℂ d ⊗ ℂ d . One case of the problem has been reduced to proving a matrix inequality when d = 4 .
