Hamiltonian diffeomorphisms of toric manifolds

Andrés Viña

We prove that $π_{1} (Ham (M))$ contains an infinite cyclic subgroup, where $Ham (M)$ is the Hamiltonian group of the one point blow up of $C P^{3}$ . We give a suffici…

A Characteristic Number of Hamiltonian Bundles over $S^{2}$

Andrés Viña

Each loop $ψ$ in the group $Ham (M)$ of Hamiltonian diffeomorphisms of a symplectic manifold $M$ determines a fibration $E$ on $S^{2}$ , whose coupling class \cite{G-L-S} is den…
