循环开-闭映射与霍奇结构的变分

The cyclic open--closed map and variations of Hodge structures

Sheel Ganatra, Nick Sheridan

AI总结:

本文在半正情形下为体形变的相对Fukaya范畴构造循环开-闭映射,证明其是半无限霍奇结构极化变分的态射,并给出同构判据,从而在Calabi-Yau镜像对中由同调镜像对称推出枚举镜像对称。

摘要:

我们在半正情形下为大的(即体形变的)相对Fukaya范畴构造了循环开-闭映射,并证明它是“半无限霍奇结构的极化变分”的一个态射。我们还给出了该映射为同构的一个自然判据,该判据在例如Batyrev镜像对的背景下得到了验证。我们在此类Calabi-Yau情形下得出结论:有理Gromov-Witten不变量可以从相对Fukaya范畴中提取,因此枚举镜像对称是Calabi-Yau镜像对的同调镜像对称的一个推论。

英文摘要:

We construct the cyclic open--closed map for the big (i.e., bulk-deformed) relative Fukaya category, in the semipositive case, and show that it is a morphism of `polarized variations of semi-infinite Hodge structures'. We also give a natural criterion for the map to be an isomorphism, which is verified for example in the context of Batyrev mirror pairs. We conclude in such Calabi-Yau cases that the rational Gromov--Witten invariants can be extracted from the relative Fukaya category, and hence that enumerative mirror symmetry is a consequence of homological mirror symmetry for Calabi--Yau mirror pairs.
