Lie Group Statistics and Lie Group Machine Learning Based on Souriau Lie Groups Thermodynamics & Koszul-Souriau-Fisher Metric: New Entropy Definition as Generalized Casimir Invariant Function in Coadjoint Representation [PDF]

open access: goldEntropy, 2020
In 1969, Jean-Marie Souriau introduced a “Lie Groups Thermodynamics” in Statistical Mechanics in the framework of Geometric Mechanics. This Souriau’s model considers the statistical mechanics of dynamic systems in their “space of evolution” associated to

On Square-Integrable Representations of A Lie Group of 4-Dimensional Standard Filiform Lie Algebra [PDF]

open access: yesCauchy: Jurnal Matematika Murni dan Aplikasi, 2020
In this paper, we study irreducible unitary representations of a real standard filiform Lie group with dimension equals 4 with respect to its basis. To find this representations we apply the orbit method introduced by Kirillov. The corresponding orbit of

Jean-Marie Souriau’s Symplectic Foliation Model of Sadi Carnot’s Thermodynamics [PDF]

open access: yesEntropy
The explanation of thermodynamics through geometric models was initiated by seminal figures such as Carnot, Gibbs, Duhem, Reeb, and Carathéodory. Only recently, however, has the symplectic foliation model, introduced within the domain of geometric ...

Variational formulation of a fully-three-dimensional non-linear beam dynamics by a Lie-group representation

open access: goldAIMS Mathematics
This paper presents a survey of a geometrically exact beam theory formulated within the framework of Lie groups, aimed at providing a mathematically consistent description of slender structures undergoing large displacements and rotations.

The representation ring of a compact Lie group revisited

open access: bronzeCommentarii Mathematici Helvetici, 1998
We describe a new construction of the induction homomorphism for representation rings of compact Lie groups: a homomorphism first defined by Graeme Segal. The idea is to first define the induction homomorphism for class functions, and then show that this map sends characters to characters.

Wavelet transforms associated to a principal series representation of semisimple Lie groups, I [PDF]

open access: bronzeProceedings of the Japan Academy, Series A, Mathematical Sciences, 1995
Let \(G\) be a locally compact Lie group and \(\pi\) a continuous representation of \(G\) on a Hilbert space \({\mathcal H}\). Let \({\mathcal H}_\infty\) denote the space of \(C^\infty\)-vectors in \({\mathcal H}\), endowed with a natural Sobolev-type topology, and \({\mathcal H}_{- \infty}\) the dual of \({\mathcal H}_\infty\) endowed with the strong

On the Unitarized Adjoint Representation of a Semisimple Lie Group II [PDF]

open access: bronzeCanadian Journal of Mathematics, 1977
Let G be a connected semisimple Lie group with Lie algebra . Lebesgue measure on is invariant under the adjoint action of G; and so there is a natural unitary representation TG of G on L2 given ...

Manifold Contrastive Learning with Variational Lie Group Operators [PDF]

open access: yesTrans. Mach. Learn. Res., 2023
Self-supervised learning of deep neural networks has become a prevalent paradigm for learning representations that transfer to a variety of downstream tasks. Similar to proposed models of the ventral stream of biological vision, it is observed that these
