For any closed symplectic manifold, we show that the number of 1-periodic orbits of a nondegenerate Hamiltonian thereon is bounded from below by a version of total Betti number over Z of the ambient space taking account of the total Betti number over Q and torsions of all characteristic. The proof is based on constructing a Hamiltonian Floer theory over the Novikov ring with integer coefficients, which generalizes our earlier work for constructing integer-valued Gromov-Witten type invariants…

Framed $E^2$ structures in Floer theory

We resolve the long-standing problem of constructing the action of the operad of framed (stable) genus-0 curves on Hamiltonian Floer theory; this operad is equivalent to the framed E2 operad. We

A local-to-global inequality for spectral invariants and an energy dichotomy for Floer trajectories

We study a local-to-global inequality for spectral invariants of Hamiltonians whose supports have a “large enough” tubular neighborhood on semipositive symplectic manifolds. In particular, we present
