关于扭曲的Rabinowitz-Floer同调讲义

Lectures on Twisted Rabinowitz-Floer Homology

Yannis Bähni

AI总结:

本文提出了一种扭曲Rabinowitz-Floer同调理论,用于研究对称星形超曲面商空间上的非可缩Reeb轨道存在性,并证明了相关强制定理。

摘要:

Rabinowitz-Floer同调是Floer所关联的Morse-Bott同调,与Kai Cieliebak和Urs Frauenfelder于2009年引入的Rabinowitz作用泛函相关。在本文中,我们考虑将此理论推广到Liouville自同构的Rabinowitz-Floer同调。作为应用,我们证明了对称星形超曲面商空间上非可缩的Reeb轨道的存在性。特别是,此理论适用于Lens空间。此外,我们证明了一个强制定理,该定理保证了在具有可缩扭曲闭特征的Morse-Bott分量中存在一个可缩扭曲闭特征,其能量差小于或等于可移动超曲面的位移能量。

英文摘要:

Rabinowitz-Floer homology is the Morse-Bott homology in the sense of Floer associated with the Rabinowitz action functional introduced by Kai Cieliebak and Urs Frauenfelder in 2009. In this manuscript, we consider a generalisation of this theory to a Rabinowitz-Floer homology of a Liouville automorphism. As an application, we show the existence of noncontractible periodic Reeb orbits on quotients of symmetric star-shaped hypersurfaces. In particular, this theory applies to lens spaces. Moreover, we prove a forcing theorem, which guarantees the existence of a contractible twisted closed characteristic on a displaceable twisted stable hypersurface in a symplectically aspherical geometrically bounded symplectic manifold if there exists a contractible twisted closed characteristic belonging to a Morse-Bott component, with energy difference smaller or equal to the displacement energy of the displaceable hypersurface.
