AI总结:

本文提出并部分验证了局部共形辛流形上的Weinstein猜想推广,引入Reeb 2-曲线,并利用Gromov-Witten理论构造Fuller指标,获得经典Reeb动力学新结果。

摘要:

我们将Weinstein猜想直接推广到闭的、Lichnerowicz精确的、局部共形辛流形(简称$\lcs$流形)上。该猜想断言流形中存在某些2-曲线,我们称之为Reeb 2-曲线。该猜想对所有闭的精确lcs曲面显然成立。在更高维数中,我们基于在$\lcs$流形中取值的某些扩展的($\mathbb{Q}^{} \sqcup \{\pm\infty\}$值)Gromov-Witten椭圆曲线计数,给出了该猜想的部分验证。作为一个基本应用,我们在经典Reeb动力学中获得了一些新结果。其中最基本的结果给出了严格接触同胚在闭接触流形上固定某个闭Reeb轨道像的充分条件。在此过程中,我们给出了经典动力学Fuller指标(对于Reeb向量场)的Gromov-Witten理论构造,该构造除其他外解释了其合理性。

英文摘要:

We introduce a direct generalization of the Weinstein conjecture to closed, Lichnerowicz exact, locally conformally symplectic manifolds, (for short $\lcs$ manifolds). This conjectures existence of certain 2-curves in the manifold, which we call Reeb 2-curves. The conjecture readily holds for all closed exact lcs surfaces. In higher dimensions, we give partial verifications of this conjecture, based on certain extended ($\mathbb{Q} ^{} \sqcup \{\pm \infty\}$ valued) Gromov-Witten, elliptic curve counts in $\lcs$ manifolds. As a basic application we get some novel results in classical Reeb dynamics. The most basic such result gives sufficient conditions for a strict contactomorphism to fix the image of some closed Reeb orbit on a closed contact manifold. Along the way we give a Gromov-Witten theoretic construction of the classical dynamical Fuller index (for Reeb vector field), which among other things explains its rationality.
