A remark on the c--splitting conjecture

Stefan Haller

Let $M$ be a closed symplectic manifold and suppose $M \to P \to B$ is a Hamiltonian fibration. Lalonde and McDuff raised the question whether one always has $H^*(P;\mathbb Q)=H^*(M;…

Non-contractible periodic trajectories of symplectic vector fields, Floer cohomology and symplectic torsion

Dan Burghelea, Stefan Haller

For a closed symplectic manifold $(M, ω)$ , a compatible almost complex structure $J$ , a 1-periodic time dependent symplectic vector field $Z$ and a homotopy class of closed curves $…
