The relation between the symplectic group Sp(4,R) and its Lie algebra: Applications to polymer quantum mechanics [PDF]

open access: yesPhysical Review D, 2021
In this paper, we show the relation between $sp(4,\mathbb{R})$, the Lie algebra of the symplectic group, and the elements of $Sp(4,\mathbb{R})$. We use this result to obtain some special cases of symplectic matrices relevant to the study of squeezed ...

Survey on Lie Group Machine Learning

open access: yesBig Data Mining and Analytics, 2020
Lie group machine learning is recognized as the theoretical basis of brain intelligence, brain learning, higher machine learning, and higher artificial intelligence. Sample sets of Lie group matrices are widely available in practical applications.

SCENE CLASSIFICATION BASED ON THE INTRINSIC MEAN OF LIE GROUP [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
Remote Sensing scene classification aims to identify semantic objects with similar characteristics from high resolution images. Even though existing methods have achieved satisfactory performance, the features used for classification modeling are still ...

Cohomology of nonabelian embedding tensors on Hom-Lie algebras

open access: yesAIMS Mathematics, 2023
In this paper, we generalize known results of nonabelian embedding tensor to the Hom setting. We introduce the concept of Hom-Leibniz-Lie algebra, which is the basic algebraic structure of nonabelian embedded tensors on Hom-Lie algebras and can also be ...

Lie Group Equivariant Convolutional Neural Network Based on Laplace Distribution

open access: yesRemote Sensing, 2023
Traditional convolutional neural networks (CNNs) lack equivariance for transformations such as rotation and scaling. Consequently, they typically exhibit weak robustness when an input image undergoes generic transformations.

Bosonic Representation of Matrices and Angular Momentum Probabilistic Representation of Cyclic States

open access: yesEntropy, 2023
The Jordan–Schwinger map allows us to go from a matrix representation of any arbitrary Lie algebra to an oscillator (bosonic) representation. We show that any Lie algebra can be considered for this map by expressing the algebra generators in terms of the

Symmetry-resolved entanglement entropy in Wess-Zumino-Witten models

open access: yesJournal of High Energy Physics, 2021
We consider the problem of the decomposition of the Rényi entanglement entropies in theories with a non-abelian symmetry by doing a thorough analysis of Wess-Zumino-Witten (WZW) models.

The universal representation kernel of a Lie group [PDF]

open access: yesProceedings of the American Mathematical Society, 1960
Let G be a connected real Lie group. The universal representation kernel, Ko, oi G is defined as the intersection of all kernels of continuous finite dimensional representations of G. Evidently, Ko is a closed normal subgroup of G, and it is known from a theorem due to Goto (cf.
