Computation of annular capacity by Hamiltonian Floer theory of non-contractible periodic trajectories

Morimichi Kawasaki, Ryuma Orita

The first author introduced a relative symplectic capacity C for a symplectic manifold (N,ωN​) and its subset X which measures the existence of non-contractible periodic traj…

On the existence of infinitely many non-contractible periodic orbits of Hamiltonian diffeomorphisms of closed symplectic manifolds

Ryuma Orita

We show that the presence of a non-contractible one-periodic orbit of a Hamiltonian diffeomorphism of a connected closed symplectic manifold (M,ω) implies the existence of infini…
