Singular values of a real rectangular tensor

Journal of Mathematical Analysis and Applications, 2010
Eigenvalues for real square tensors have been introduced and nice properties such as the Perron-Frobenius theorem for eigenvalues of nonnegative square tensors have been obtained in recent years. Real rectangular tensors arise from the strong ellipticity condition problem in solid mechanics and the entanglement problem in quantum physics. In this paper

Rectangular array of electromagnetic vector sensors: tensor modelling/decomposition and DOA‐polarisation estimation [PDF]

IET Signal Processing, 2019
In this study, the authors propose a fast quadrilinear decomposition algorithm for estimation of the directions‐of‐arrival and polarisations of the incident sources via a uniform rectangular array of electromagnetic vector sensors (EMVSs). Conventional quadrilinear alternating least squares (QALS), involves computationally intensive Khatri‐Rao products

Convergence of an algorithm for the largest singular value of a nonnegative rectangular tensor

Linear Algebra and its Applications, 2013
The authors present an iterative algorithm for computing the largest singular value of a nonnegative rectangular tensor. The convergence of this algorithm for any irreductibile nonnegative rectangular tensor is also proved.

Vortices with laminar and turbulent flow patterns in anisotropic media

Технічна інженерія, 2023
The study develops and describes, in general, new models and devices of energy converters. The proposed devices operate on the basis of a rectangular parallelepiped with length a, height b, and width c ( ) made of anisotropic material.

Some inequalities and numerical results estimating error of approximation for tensor product kind bivariate quantum beta-type operators and pertaining to GBS variant

Journal of Inequalities and Applications, 2022
In this study, we investigate some inequalities estimating the error of approximation for new defined tensor product kind quantum beta-type operators on rectangular regions, and we give an inequality in weighted mean.

Fundamental Invariants of Tensors, Latin Hypercubes, and Rectangular Kronecker Coefficients

International Mathematics Research Notices, 2022
Abstract We study polynomial SL-invariants of tensors, mainly focusing on fundamental invariants that are of smallest degrees. In particular, we prove that certain 3-dimensional analogue of the Alon–Tarsi conjecture on Latin cubes considered previously by Bürgisser and Ikenmeyer implies positivity of (generalized) Kronecker coefficients ...

Blind signal separation for coprime planar arrays: An improved coupled trilinear decomposition method

ETRI Journal, 2023
In this study, the problem of blind signal separation for coprime planar arrays is investigated. For coprime planar arrays comprising two uniform rectangular subarrays, we link the signal separation to the tensor-based model called coupled canonical ...

A new S-type upper bound for the largest singular value of nonnegative rectangular tensors

Journal of Inequalities and Applications, 2017
By breaking N = { 1 , 2 , … , n } $N=\{1,2,\ldots,n\}$ into disjoint subsets S and its complement, a new S-type upper bound for the largest singular value of nonnegative rectangular tensors is given and proved to be better than some existing ones ...
