无理辛流形的Conley猜想

The Conley conjecture for irrational symplectic manifolds

Doris Hein

摘要:

我们证明了Conley猜想的一个推广:如果第一类Chern类在第二个基本群上为零,则闭辛流形的每个Hamilton双同态都有无穷多个周期轨道.特别是,我们从类似的结果中删除了合理性条件。无理情形下的证明涉及到几个新的思想,包括无理流形上Hamilton算子的滤弗洛尔同调的定义和性质。我们还开发了一种方法,本地化的过滤弗洛尔同调短的动作间隔使用直和分解,其中的一个被加数只取决于在一个固定的开集的哈密尔顿的行为。

英文摘要:

We prove a generalization of the Conley conjecture: Every Hamiltonian diffeomorphism of a closed symplectic manifold has infinitely many periodic orbits if the first Chern class vanishes over the second fundamental group. In particular, we this removes the rationality condition from similar results. The proof in the irrational case involves several new ideas including the definition and the properties of the filtered Floer homology for Hamiltonians on irrational manifolds. We also develop a method of localizing the filtered Floer homology for short action intervals using a direct sum decomposition, where one of the summands only depends on the behavior of the Hamiltonian in a fixed open set.
