AI总结:

该研究探讨了双曲闭Reeb轨道对动力学的影响,证明了其存在意味着无限多个简单闭轨道,并推广了Le Calvez-Yoccoz定理至Reeb情形。

摘要:

我们研究了双曲(或更一般地说,作为不变集)闭Reeb轨道对标准接触球上Reeb流动力学的影响,将此前已知的两个关于Hamiltonian微分同胚的结果扩展到Reeb情形。特别是,我们证明在非常温和的动力凸性假设下,一个双曲闭轨道的存在意味着存在无限多个简单闭Reeb轨道。论文的第二个主要结果是Reeb情形下的Le Calvez-Yoccoz定理的高维推广,断言非退化动力学凸Reeb伪旋转的闭轨道不是局部最大值,即作为不变集隔离。证明的关键新成分是Reeb变体的交叉能量定理。

英文摘要:

We investigate the effect of a hyperbolic (or, more generally, isolated as an invariant set) closed Reeb orbit on the dynamics of a Reeb flow on the $(2n-1)$-dimensional standard contact sphere, extending two results previously known for Hamiltonian diffeomorphisms to the Reeb setting. In particular, we show that under very mild dynamical convexity type assumptions, the presence of one hyperbolic closed orbit implies the existence of infinitely many simple closed Reeb orbits. The second main result of the paper is a higher-dimensional Reeb analogue of the Le Calvez-Yoccoz theorem, asserting that no closed orbit of a non-degenerate dynamically convex Reeb pseudo-rotation is locally maximal, i.e., isolated as an invariant set. The key new ingredient of the proofs is a Reeb variant of the crossing energy theorem.
