Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2021 The paper deals with the problems of ordering the reper orientations for a micropolar continuum immersed in an external plane space. Based on the concept of an elementary tensor volume (area) \(M\)-cells, an algorithm for comparing and matching external ...

Distinguishing Random and Black Hole Microstates
PRX Quantum, 2021 In this work, we study the distinguishability of random states drawn from the Wishart ensemble as well as black hole microstates. We compute the relative entropy and many generalizations, including the Petz Rényi relative entropy, sandwiched Rényi ...

Randomized CP tensor decomposition [PDF]
Machine Learning: Science and Technology, 2017 The CANDECOMP/PARAFAC (CP) tensor decomposition is a popular dimensionality-reduction method for multiway data. Dimensionality reduction is often sought after since many high-dimensional tensors have low intrinsic rank relative to the dimension of the ...

Gravitational Waves in Scalar–Tensor–Vector Gravity Theory
Universe, 2021 In this paper, we study the properties of gravitational waves in the scalar–tensor–vector gravity theory. The polarizations of the gravitational waves are investigated by analyzing the relative motion of the test particles.

Polynomial-Time Tensor Decompositions with Sum-of-Squares [PDF]
IEEE Annual Symposium on Foundations of Computer Science, 2016 We give new algorithms based on the sum-of-squares method for tensor decomposition. Our results improve the best known running times from quasi-polynomial to polynomial for several problems, including decomposing random overcomplete 3-tensors and ...

The space generated by metric and torsion tensors, derivation of Einstein-Hilbert equation
Pracì Mìžnarodnogo Geometričnogo Centru, 2014 This paper is devoted to the derivation of field equations in space with the geometric structure generated by metric and torsion tensors. We also study the geometry of the space are generated jointly and agreed by the metric tensor and the torsion tensor.

A Full-Body Relative Orbital Motion of Spacecraft Using Dual Tensor Algebra and Dual Quaternions
Mathematics, 2023 This paper proposes a new non-linear differential equation for the six degrees of freedom (6-DOF) relative rigid bodies motion. A representation theorem is provided for the 6-DOF differential equation of motion in the arbitrary non-inertial reference ...

Implementable tensor methods in unconstrained convex optimization
Mathematical programming, 2019 In this paper we develop new tensor methods for unconstrained convex optimization, which solve at each iteration an auxiliary problem of minimizing convex multivariate polynomial.

Neutrino and antineutrino quasielastic interactions with nuclei [PDF]
, 2010 We investigate the interaction of neutrinos and antineutrinos with nuclei. We explore in particular the role played by the multinucleon excitations which can contaminate the quasielastic cross section.
