Question about an example in symplectic geometry
Let M be a coadjoint orbit of dimension 6 of $SU(3)$, and let T be the maximal torus in $SU(3)$. If we denote $\mu : M \longrightarrow \mathbb{R}^2$ the moment map associated to the action of T on M, ...

$TSU(n)$ completely integrable with 3 $SU(2)$ invariant functions?
Consider the Lie group $SU(n)$ endowed with the standard bi-invariant metric. Then $SU(n)$ can be viewed as a symmetric space of $K_{n,n} := SU(n) \times SU(n)$.
Define $M := K_{n,n} /SU(n)$. Using ...

set of coisotropic orbits open and dense, iff group acts locally transitively almost everywhere
I worked now some time with coisotropic actions of Liegroups on manifolds.
But there is one key fact, that I don't understand, although it is very central in my considerations.
Let $(M,\omega)$ be a ...
