Representations of Lie algebras and Lie groupsTaylor joint spectrumWe study non-skewselfadjoint representations of a finite dimensional real Lie algebrag. To this end we embed a non-skewselfadjoint representation ofginto a more complicated structure, that we call ag-operator vessel and that is ...
Thus the adjoint representation of G on g induces a co-adjoint representation of G on the dual g* of its Lie algebra g, i.e. on the cotangent space to the group G at the identity, g* = T*e G. The co-adjoint representation will play a central role in symplectic reduction (starting...
I have trouble understanding the definition of the coadjoint representation of a Lie algebra. Typically you first define a natural pairing between the Lie algebra and Lie coalgebra: ⟨,⟩:g∗×g→R⟨,⟩:g∗×g→R I don't really understand how this is defined, the literature ...
I am having trouble understanding the adjoint representation of a Lie algebra in the scope of a very specific example, so I thought physics.SE would be the best place to ask. Background: A $N \times N$ density matrix $\rho$ contains only $N^2 - 1$ non-redundant real quantities. The...

The purpose of this article is to study in detail the actions of a semisimple Lie or algebraic group on its Lie algebra by the adjoint representation and on itself by the adjoint action. We will focus primarily on orbits through nilpotent elements in the Lie algebra; these are called nilpoten...

For AdjointMatrix(L) to make sense, the LAVF object L must be a Lie algebra (i.e. IsLieAlgebra(L) returns true. See IsLieAlgebra for more detail). • In the second calling sequence, AdjointMatrix(L,M) returns a matrix representation of the Lie algebra L on the invariant subspace...
Let G be a p-adic Lie group with Lie algebra and Ad: G鈫扐ut() be the adjoint representation. It was claimed in the literature that the kernel Kker(Ad) always has an abelian open normal subgroup. We show by means of a counterexample that this assertion is false. It can even happen...
