AI总结:

该研究建立了Liouville域完备化中Poisson括号不变量的下界,用缠绕Floer同调的条形码表示,并以闭Riemann流形余切丛的构型为主要示例。

摘要:

由Buhovsky、Entov和Polterovich引入,并由Entov和Polterovich进一步研究的Poisson括号不变量,可作为辛流形中闭集四元组的不变量。其非零性对四元组内集合对之间存在Hamiltonian弦具有重要意义,且对这些弦的时间长度有界限限制。在本工作中,我们为Liouville域完备化中出现的某些构型建立了Poisson括号不变量的下界。这些下界以缠绕Floer同调的条形码表示。我们的主要例子来自闭Riemann流形的余切丛,其中四元组由不同点上的两根纤维和不同半径的两个余球丛,或单个余球丛与零截面组成。

英文摘要:

The Poisson bracket invariants, introduced by Buhovsky, Entov, and Polterovich and further studied by Entov and Polterovich, serve as invariants for quadruples of closed sets in symplectic manifolds. Their nonvanishing has significant implications for the existence of Hamiltonian chords between pairs of sets within the quadruple, with bounds on the time-length of these chords. In this work, we establish lower bounds on the Poisson bracket invariants for certain configurations arising in the completion of Liouville domains. These bounds are expressed in terms of the barcode of wrapped Floer homology. Our primary examples come from cotangent bundles of closed Riemannian manifolds, where the quadruple consists of two fibers over distinct points and two cosphere bundles of different radii, or a single cosphere bundle and the zero section.
