Periodic Hamiltonian Flows on Four Dimensional Manifolds

چکیده
We classify the periodic Hamiltonian flows on compact four dimensional symplectic manifolds up to isomorphism of Hamiltonian S-spaces. Additionally, we show that all these spaces are Kähler, that every such space is obtained from a simple model by a sequence of symplectic blowups, and that if the fixed points are isolated then the space is a toric variety.

An Integer Optimization Problem for Non-hamiltonian Periodic Flows
Let C be the class of compact 2n-dimensional symplectic manifolds (M,ω) for which the first or (n − 1) Chern class vanish. We point out an integer optimization problem to find a lower bound B(n) on the number of equilibrium points of non-Hamiltonian symplectic periodic flows on manifolds (M,ω) ∈ C. As a consequence, we confirm in dimensions 2n ∈ {8, 10, 12, 14, 18, 20, 22} a conjecture for unit...
متن کاملSymplectic Field Theory Approach to Studying Ergodic Measures Related with Nonautonomous Hamiltonian Systems
An approach to studying ergodic properties of time-dependent periodic Hamiltonian flows on symplectic metric manifolds is developed. Such flows have applications in mechanics and mathematical physics. Based both on J. Mather’s results [9] about homology of probability invariant measures minimizing some Lagrangian functionals and on the symplectic field theory devised by A. Floer and others [3]–...
متن کاملThe Hamiltonian Seifert Conjecture: Examples and Open Problems
Hamiltonian dynamical systems tend to have infinitely many periodic orbits. For example, for a broad class of symplectic manifolds almost all levels of a proper smooth Hamiltonian carry periodic orbits. The Hamiltonian Seifert conjecture is the existence problem for regular compact energy levels without periodic orbits. Very little is known about how large the set of regular energy values witho...
متن کاملMaslov Class Rigidity for Lagrangian Submanifolds via Hofer’s Geometry
In this work, we establish new rigidity results for the Maslov class of Lagrangian submanifolds in large classes of closed and convex symplectic manifolds. Our main result establishes upper bounds for the minimal Maslov number of displaceable Lagrangian submanifolds which are product manifolds whose factors each admit a metric of negative sectional curvature. Such Lagrangian submanifolds exist ...
متن کاملGeneric Dynamics of 4-dimensional C Hamiltonian Systems
We study the dynamical behaviour of Hamiltonian flows defined on 4-dimensional compact symplectic manifolds. We find the existence of a C-residual set of Hamiltonians for which every regular energy surface is either Anosov or it is in the closure of energy surfaces with zero Lyapunov exponents a.e. This is in the spirit of the Bochi-Mañé dichotomy for area-preserving diffeomorphisms on compact ...
