Fixed points of symplectic tranformations
Let (M,ω) be a closed symplectic manifold. Given a function H : M → R the Hamiltonian vector field XH determined by the Hamiltonian H is defined by the formula XH ω = −dH. Then LXHω = 0, and hence the flow generated by XH preserves the symplectic form ω. If one has a family of functions Ht : M → R, t ∈ [0, 1], one gets a family of Hamiltonian vector fields XHt which generate an isotopy ft : M →...
متن کاملSymplectic Invariants near Hyperbolic-Hyperbolic Points
We construct symplectic invariants for Hamiltonian integrable systems of 2 degrees of freedom possessing a fixed point of hyperbolichyperbolic type. These invariants consist in some signs which determine the topology of the critical Lagrangian fibre, together with several Taylor series which can be computed from the dynamics of the system. We show how these series are related to the singular as...
متن کاملFixed points of symplectic periodic flows
The study of fixed points is a classical subject in geometry and dynamics. If the circle acts in a Hamiltonian fashion on a compact symplectic manifoldM , then it is classically known that there are at least dim M 2 +1 fixed points; this follows fromMorse theory for the momentum map of the action. In this paper we use Atiyah-Bott-Berline-Vergne (ABBV) localization in equivariant cohomology to p...
متن کاملSeiberg-Witten invariants of mapping tori, symplectic fixed points, and Lefschetz numbers
Let f : Σ → Σ be an orientation preserving diffeomorphism of a compact oriented Riemann surface. This paper relates the Seiberg-Witten invariants of the mapping torus Yf to the Lefschetz invariants of f .
متن کاملEffective generic super-exponential stability of elliptic fixed points for symplectic vector fields
In this article, we consider linearly stable elliptic fixed points (equilibrium) for a symplectic vector field and we prove generic results of super-exponential stability for nearby solutions. We will focus on the neighbourhood of elliptic fixed points but the case of linearly stable isotropic reducible invariant tori in an Hamiltonian system should be similar. More specifically, Morbidelli and...
