论带边Floer同调中的切触不变量

On contact invariants in bordered Floer homology

Hyunki Min, Konstantinos Varvarezos

AI总结:

本文在带边缝合Floer同调中定义了适用范围更广的切触不变量,证明其满足配对定理,建立了$\u2070\mathcal{A}_{\infty}$运算与旁路粘贴映射的对应关系,并给出相关应用与切触手术结果。

摘要:

本文定义了带边缝合Floer同调中的切触不变量。针对具有凸边界的切触3-流形,我们利用Zarev(arxiv:1010.3496)的结果,推导了带边缝合模$\u2070\widehat{\mathit{BSA}}$和$\u2070\widehat{\mathit{BSD}}$中的切触不变量,以及在具有两个边界分支的情况下,双模$\u2070\widehat{\mathit{BSAA}}$、$\u2070\widehat{\mathit{BSDD}}$、$\u2070\widehat{\mathit{BSDA}}$中的切触不变量。在边界连通的情形下,只要Alishahi-Földvári-Hendricks-Licata-Petkova-Vértesi(arxiv:2011.08672)定义的带边切触不变量有定义,我们的不变量就与其一致,且我们的不变量可在更广泛的语境下定义。我们证明这些不变量满足配对定理,该定理是缝合Floer同调中Honda-Kazez-Matić粘合映射(arxiv:0705.2828)的带边推广。我们还表明,带边A型模中的某些$\u2070\mathcal{A}_{\infty}$运算与缝合Floer同调中的旁路粘贴映射之间存在对应关系。作为应用,我们将从$\u2070\mathit{SFH}$到$\u2070\widehat{\mathit{HFK}}$的Stipsicz-Vértesi映射刻画为$\u2070\widehat{\mathit{CFA}}$上的$\u2070\mathcal{A}_{\infty}$作用。我们还利用Hanselman-Rasmussen-Watson(arxiv:1604.03466)的浸入曲线解释,证明了与切触手术相关的结果。

英文摘要:

In this paper, we define contact invariants in bordered sutured Floer homology. Given a contact 3-manifold with convex boundary, we apply a result of Zarev (arxiv:1010.3496) to derive contact invariants in the bordered sutured modules $\widehat{\mathit{BSA}}$ and $\widehat{\mathit{BSD}}$, as well as in bimodules $\widehat{\mathit{BSAA}},$ $\widehat{\mathit{BSDD}},$ $\widehat{\mathit{BSDA}}$ in the case of two boundary components. In the connected boundary case, our invariants appear to agree with bordered contact invariants defined by Alishahi-Földvári-Hendricks-Licata-Petkova-Vértesi (arxiv:2011.08672) whenever the latter are defined, although ours can be defined in broader contexts. We prove that these invariants satisfy a pairing theorem, which is a bordered extension of the Honda-Kazez-Matić gluing map (arxiv:0705.2828) for sutured Floer homology. We also show that there is a correspondence between certain $\mathcal{A}_{\infty}$ operations in bordered type-$A$ modules and bypass attachment maps in sutured Floer homology. As an application, we characterize the Stipsicz-Vértesi map from $\mathit{SFH}$ to $\widehat{\mathit{HFK}}$ as an $\mathcal{A}_{\infty}$ action on $\widehat{\mathit{CFA}}$. We also apply the immersed curve interpretation of Hanselman-Rasmussen-Watson (arxiv:1604.03466) to prove results involving contact surgery.
