Regularly Decomposable Tensors and Classical Spin States [PDF]

open access: yes, 2017
A spin-$j$ state can be represented by a symmetric tensor of order $N=2j$ and dimension $4$. Here, $j$ can be a positive integer, which corresponds to a boson; $j$ can also be a positive half-integer, which corresponds to a fermion.

Tensor factorization via transformed tensor-tensor product for image alignment

open access: yesNumerical Algorithms, 2023
In this paper, we study the problem of a batch of linearly correlated image alignment, where the observed images are deformed by some unknown domain transformations, and corrupted by additive Gaussian noise and sparse noise simultaneously. By stacking these images as the frontal slices of a third-order tensor, we propose to utilize the tensor ...

Threshold Analysis of Request Degradation in the Computer Network

open access: yesМоделирование и анализ информационных систем, 2019
In this paper, the existing approaches to the assessment of computer networks performance are considered. The standard structure of a network of the application layer of the OSI model using the example of SBIS3 application (product of Tensor Company) is ...

Hyperspectral Image Dimension Reduction Using Weight Modified Tensor-Patch-Based Methods

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
Dimension reduction (DR) addresses the problem known as the curse of dimensionality in myriad hyperspectral imagery applications. Although the spatial pattern may assist in the distinction between different land covers that have close spectral signatures,

Abelian tensors

open access: yesJournal de Mathématiques Pures et Appliquées, 2017
We analyze tensors in the tensor product of three m-dimensional vector spaces satisfying Strassen's equations for border rank m. Results include: two purely geometric characterizations of the Coppersmith-Winograd tensor, a reduction to the study of symmetric tensors under a mild genericity hypothesis, and numerous additional equations and examples ...

New electromagnetic conservation laws [PDF]

open access: yes, 2003
The Chevreton superenergy tensor was introduced in 1964 as a counterpart, for electromagnetic fields, of the well-known Bel-Robinson tensor of the gravitational field.

A note on the gap between rank and border rank [PDF]

open access: yes, 2017
We study the tensor rank of the tensor corresponding to the algebra of n-variate complex polynomials modulo the dth power of each variable. As a result we find a sequence of tensors with a large gap between rank and border rank, and thus a counterexample

A constructive arbitrary-degree Kronecker product decomposition of tensors [PDF]

open access: yes, 2016
We propose the tensor Kronecker product singular value decomposition~(TKPSVD) that decomposes a real $k$-way tensor $\mathcal{A}$ into a linear combination of tensor Kronecker products with an arbitrary number of $d$ factors $\mathcal{A} = \sum_{j=1}^R ...
