Homology of the Lie algebra of vector fields on the line with coefficients in symmetric powers of its adjoint representation [PDF]

open access: yesFunctional Analysis and Its Applications, 2006
We compute the homology of the Lie algebra~$W_1$ of (polynomial)vector fields on a line with coefficients in symmetric powersof its adjoint representation. We also list the results obtained so farfor the homology with coefficients in tensor powers and, in turn, use themfor partially computing the homology of the Liealgebra of currents on a line with ...

Useful relations among the generators in the defining and adjoint representations of SU(N)

open access: yesSciPost Physics Lecture Notes, 2021
There are numerous relations among the generators in the defining and adjoint representations of SU(N). These include Casimir operators, formulae for traces of products of generators, etc.

Deformations of the three-dimensional Lie algebra sl(2)

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2020
Deformation is one of key questions of the structural theory of algebras over a field. Especially, it plays a important role in the classification of such algebras.

Lie point symmetry infinitesimals, optimal system, power series solution, and modulational gain spectrum to the mathematical Noyes–Field model of nonlinear homogeneous oscillatory Belousov–Zhabotinsky reaction

open access: yesResults in Physics, 2023
Introduction:: The chemical oscillators are identified as open system that demonstrate periodic changes in the concentration of some reaction species as a result of intricate physico-chemical mechanisms which can lead to bi-stability, the occurrence of ...

Multiplicity of the Adjoint Representation in Simple Quotients of the Enveloping Algebra of a Simple Lie Algebra [PDF]

open access: yesTransactions of the American Mathematical Society, 1989
Let g \mathfrak {g} be a complex simple Lie algebra, h \mathfrak {h} a Cartan subalgebra and U ( g ) U(\mathfrak {g}) the enveloping algebra of g \mathfrak {g} . We calculate for each maximal two-sided

Geometric Theory of Heat from Souriau Lie Groups Thermodynamics and Koszul Hessian Geometry: Applications in Information Geometry for Exponential Families

open access: yesEntropy, 2016
We introduce the symplectic structure of information geometry based on Souriau’s Lie group thermodynamics model, with a covariant definition of Gibbs equilibrium via invariances through co-adjoint action of a group on its moment space, defining physical ...

Extended geometries

open access: yesJournal of High Energy Physics, 2018
We present a unified and completely general formulation of extended geometry, characterised by a Kac-Moody algebra and a highest weight coordinate module.

BPS Center Vortices in Nonrelativistic SU(N) Gauge Models with Adjoint Higgs Fields

open access: yesAdvances in High Energy Physics, 2015
We propose a class of SU(N) Yang-Mills models, with adjoint Higgs fields, that accept BPS center vortex equations. The lack of a local magnetic flux that could serve as an energy bound is circumvented by including a new term in the energy functional ...

Non-finitary Generalizations of Nil-triangular Subalgebras of Chevalley Algebras

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2019
Let $N\Phi(K)$ be a niltriangular subalgebra of Chevalley algebra over a field or ring $K$ associated with root system $\Phi$ of classical type. For type $A_{n-1}$ it is associated to algebra $NT(n,K)$ of (lower) nil-triangular $n \times n$- matrices ...
