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

On the Stiefel-Whitney class of the adjoint representation of $E_8$ [PDF]
Kyoto Journal of Mathematics, 2004 Let $\widetilde{E}_8$ be the 3-connected covering space of the 1-connected, compact exceptional group $E_8$, which is regarded as the loop space of the homotopy fibre $B\widetilde{E}_8$ of a map from $BE_8$, the classifying space of $E_8$, to an Eilenberg-MacLane space.

The spectrum of the adjoint representation and the hyperbolicity of dynamical systems
Journal of Differential Equations, 1980 Let (M,g) denote a smooth compact Riemannian manifold. Anosov [I] defined the global hypcrbolicity of a C2 diffeomorphism (resp. a nonsingular flow f’) on M :f (resp. fr) is h yperbolic or, as we shall say, Anosov, if the tangent bundle TM splits as a sum of invariant subbundles TM = E’ ~3 E(resp. TM = B @ E@ [A’, where [X7 is th I e ine bundle spanned

On the geometry of the adjoint representation of a Chevalley group
Journal of Algebra, 1989 AbstractWe prove that the adjoint module of a Chevalley group (not of type Cl) has a presentation by long root subalgebras, subject to certain relations determined by the minimal parabolic subgroups.

Exterior Powers of the Adjoint Representation
Canadian Journal of Mathematics, 1997 AbstractExterior powers of the adjoint representation of a complex semisimple Lie algebra are decomposed into irreducible representations, to varying degrees of satisfaction.

Representations are adjoint to endomorphisms [PDF]
Journal of Homotopy and Related Structures, 2019 The functor that takes a ring to its category of modules has an adjoint if one remembers the forgetful functor to abelian groups: the endomorphism ring of linear natural transformations. This uses the self-enrichment of the category of abelian groups. If one considers enrichments into symmetric sequences or even bisymmetric sequences, one can produce ...

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

An adjoint representation for polynomial algebras [PDF]
Proceedings 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.

Transformation groups resembling the adjoint representation [PDF]
Proceedings of the American Mathematical Society, 1975 If G G is a compact, connected Lie group, the isotropy subgroups of the adjoint representation of G G are connected and the dimension of the fixed point set of a maximal torus of G G is equal to the the rank of G G . Results similar to these are given when G G acts
