Duality in filtered Floer-Novikov complexes
Michael Usher
We prove that a certain bilinear pairing (analagous to the Poincare-Lefschetz intersection pairing) between filtered sub- and quotient complexes of a Floer-type chain complex and o…

Boundary depth in Floer theory and its applications to Hamiltonian dynamics and coisotropic submanifolds
Michael Usher
We assign to each nondegenerate Hamiltonian on a closed symplectic manifold a Floer-theoretic quantity called its "boundary depth," and establish basic results about how the bounda…
