Symplectic topology of integrable hamiltonian systems, I : Arnold-Liouville with singularities
Proper groupoids and momentum maps : linearization, affinity, and convexity
Equivariant normal form for nondegenerate singular orbits of integrable hamiltonian systems
Normal forms of vector fields on Poisson manifolds
We study formal and analytic normal forms of radial and Hamiltonian vector fields on Poisson manifolds near a singular point.
