AI总结:

本研究证明配边空间的导出缠绕Fukaya范畴、导出紧Fukaya范畴与余核圆盘构成Calabi--Yau三元组,其商范畴为对应cluster范畴且具Calabi--Yau结构,还利用该结构算出的态射空间同构于Rabinowitz Floer上同调。

摘要:

我们证明导出缠绕Fukaya范畴$D^π\backslashmathcal{W}(X_{Q}^{d+1})$、导出紧Fukaya范畴$D^π\backslashmathcal{F}(X_{Q}^{d+1})$与配边空间$X_{Q}^{d+1}$的余核圆盘$L_{Q}$构成一个Calabi--Yau三元组。由此,商范畴$D^π\backslashmathcal{W}(X_{Q}^{d+1})/D^π\backslashmathcal{F}(X_{Q}^{d+1})$成为与$Q$相关的cluster范畴,其性质之一是具有Calabi--Yau结构。此外根据Ganatra--Gao--Venkatesh的工作,该商范畴与Rabinowitz Fukaya范畴拟等价。我们利用Calabi--Yau结构计算了$L_{Q}$在上述商范畴中的态射空间,该空间同构于$L_{Q}$的Rabinowitz Floer上同调。

英文摘要:

We show that the derived wrapped Fukaya category $D^π\mathcal{W}(X_{Q}^{d+1})$, the derived compact Fukaya category $D^π\mathcal{F}(X_{Q}^{d+1})$ and the cocore disks $L_{Q}$ of the plumbing space $X_{Q}^{d+1}$ form a Calabi--Yau triple. As a consequence, the quotient category $D^π\mathcal{W}(X_{Q}^{d+1})/D^π\mathcal{F}(X_{Q}^{d+1})$ becomes the cluster category associated to $Q$. One of its properties is a Calabi--Yau structure. Also it is known that this quotient category is quasi-equivalent to the Rabinowitz Fukaya category due to the work of Ganatra--Gao--Venkatesh. We compute the morphism space of $L_{Q}$ in $D^π\mathcal{W}(X_{Q}^{d+1})/D^π\mathcal{F}(X_{Q}^{d+1})$ using the Calabi--Yau structure, which is isomorphic to the Rabinowitz Floer cohomology of $L_{Q}$.
