Torus knots in adjoint representation and Vogel’s universality [PDF]

open access: diamondEuropean Physical Journal C: Particles and Fields
Vogel’s universality gives a unified description of the adjoint sector of representation theory for simple Lie algebras in terms of three parameters $$\alpha ,\beta ,\gamma $$ α , β , γ , which are homogeneous coordinates of Vogel’s plane.

An adjoint representation for polynomial algebras [PDF]

open access: bronzeProceedings of the American Mathematical Society, 1987
This paper shows that a graded polynomial algebra over F 2 {F_2} with Steenrod algebra action possesses an analog of the adjoint representation for the cohomology of the classifying space of a compact connected Lie group.

Adjoints and low-rank covariance representation [PDF]

open access: greenNonlinear Processes in Geophysics, 2001
Abstract. Quantitative measures of the uncertainty of Earth system estimates can be as important as the estimates themselves. Direct calculation of second moments of estimation errors, as described by the covariance matrix, is impractical when the number of degrees of freedom of the system state is large and the sources of uncertainty are not ...

Lie Supergroups Obtained from 3-Dimensional Lie Superalgebras Associated to the Adjoint Representation and Having a 2-Dimensional Derived Ideal [PDF]

open access: goldInternational Journal of Mathematics and Mathematical Sciences, 2008
We give the explicit multiplication law of the Lie supergroups for which the base manifold is a 3-dimensional Lie group and whose underlying Lie superalgebra g=g0⊕g1 which satisfies g1=g0, g0 acts on g1 via the adjoint representation and g0 has a 2 ...

Rational actions associated to the adjoint representation [PDF]

open access: bronzeAnnales scientifiques de l'École normale supérieure, 1987
Let \(G\) be a simple algebraic group with Lie algebra \(\mathfrak g\). In this paper the authors prove a \(G\)-equivariant version of the Poincaré-Birkhoff-Witt theorem. In positive characteristic they also obtain analogous results for the hyperalgebras of \(G\) and of the Frobenius kernels \(G_r\), \(r\geq 1\). Extending \textit{F. D.

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.

SELF-ADJOINT REPRESENTATIONS OF BRAID GROUPS [PDF]

open access: yesJournal of Knot Theory and Its Ramifications, 2012
We give a method to construct new self-adjoint representations of 𝔹n of finite dimension. In particular, we give a family of irreducible self-adjoint representations of dimension arbitrarily large. Moreover we give sufficient condition for a representation to be constructed with this method.

Worldline description of a bi-adjoint scalar and the zeroth copy

open access: yesJournal of High Energy Physics, 2021
Bi-adjoint scalars are helpful in studying properties of color/kinematics duality and the double copy, which relates scattering amplitudes of gauge and gravity theories. Here we study bi-adjoint scalars from a worldline perspective.
