The Lie algebra dis called the double of the Lie bialgebra g. In the special case λ= 0, the double is the semi-direct product d= g⋉g∗ with respect to the coadjoint action, with h= g∗.

WebAug 8, 2024 · Meaning of the coadjoint representation and its orbits. Given a Lie group G there is a natural representation of G on the dual of its Lie algebra g ∗ given by the coadjoint representation. This representation is obtained by differentiating the diffeomorphisms given by conjugation cong(h) = ghg − 1 and then taking the adjoint.
