A Hamiltonian fibration is a fibration whose structure group reduces to the Hamiltonian symplectomorphism group of the fiber. For a Hamiltonian fibration $F\hookrightarrow P\to B$,…

The c-splitting conjecture. The spectral sequence associated to any Hamiltonian fibration degenerates at the $E_2$ term.

A Hamiltonian fibration is a fibration … of closed connected symplectic manifolds. It is rationally cohomologically split when the inclusion of the fiber induces an injective map i…
