辛几何和接触几何中的Generating functions

Generating functions in symplectic and contact geometry

Aaron Gootjes-Dreesbach

摘要:

在具有接触形式$α$的接触流形上的接触同胚$ϕ$的平移点是点$p$,其中$α$在$ϕ$下保持,并且其在$ϕ$下的像位于相同的Reeb轨迹中。它们是由Sheila Sandon作为Hamilton同构的不动点的接触类比引入的,并且可以理解为叶式不动点的特殊情况。她建立了一个接触版本的非退化Arnol'd猜想领域使用生成函数的方法。事实证明,Sandon的证明只在假设存在一个生成函数,其子水平集为零具有非平凡同调的情况下才有效。这篇硕士论文证明了在这个额外的假设下的结果,并填补了Sandon论点其他部分的小空白。

英文摘要:

A translated point of a contactomorphism $ϕ$ on a contact manifold with contact form $α$ is a point $p$ where $α$ is preserved under $ϕ$ and whose image under $ϕ$ lies in the same Reeb trajectory. They were introduced as a contact analogon for fixed points of Hamiltonian diffeomorphisms by Sheila Sandon and can be understood as a special case of leafwise fixed points. She established a contact version of the non-degenerate Arnol'd conjecture on spheres using a generating function approach. It turns out that Sandon's proof only works under the assumption that there exists a generating function whose sublevel set at zero has nontrivial homology. This master's thesis proves the result under this additional assumption and fills minor gaps in other parts of Sandon's argument.
