LetP be a symplectic manifold whose symplectic form, integrated over the spheres inP, is proportional to its first Chern class. On the loop space ofP, we consider the variational theory of the symplectic action function perturbed by a Hamiltonian term. In particular, we associate to each isolated invariant set of its gradient flow an Abelian group with a cyclic grading. It is shown to have properties similar to the homology of the Conley index in locally compact spaces. As an application, we…

A symplectic fixed point theorem for toric manifolds
In this paper, by a toric manifold we mean a non-singular symplectic quotient M = ℂ n //T k of the standard symplectic space by a linear torus action. Such a toric manifold is in fact a complex

Abstract We show that there is an hierarchy of intersection rigidity properties of sets in a closed symplectic manifold: some sets cannot be displaced by symplectomorphisms from more sets than the
J-holomorphic curves and symplectic invariants
Given an almost complex structure J on a manifold M, a map f from a Riemann surface to M is called a pseudoholomorphic (or J-holomorphic) curve if at each point p of the surface, the ordinary

We prove that the group of area-preserving diffeomorphisms of the 2-sphere admits a non-trivial homogeneous quasimorphism to the real numbers with the following property. Its value on any

Let M be a weakly monotone symplectic manifold and H be a time-dependent 1-periodic Hamiltonian; we assume that the 1-periodic orbits of the corresponding time-dependent Hamiltonian vector field are

We define Floer homology for a time-independent, or autonomous Hamiltonian on a symplectic manifold with contact type boundary, under the assumption that its 1-periodic orbits are transversally
