| Apr 29, 2012 at 20:41 | comment | added | Jonny Evans | @Tobias: Your intuition that the difference between Hamiltonian and symplectic diffeomorphisms is a topological one and Alberto's statement that the Hamiltonian diffeos form a much smaller class can be made precise in terms of the flux homomorphism. For instance on a manifold with $b_1=0$ symplectic diffeos are Hamiltonian. | |
