AI总结:

该研究通过分析辛吹胀操作下的 Fukaya 分类,展示了小参数下拉格朗日膜的分裂生成特性,并验证了最小模型程序中过渡行为对 Fukaya 分类的影响。

摘要:

我们计算了紧致有理辛流形在一点处的辛吹胀的 Fukaya 分类,具体来说:假设有若干拉格朗日膜满足 Abouzaid 对于带体变形 Fukaya 分类的分裂生成的条件。我们显示,对于小的吹胀参数,这些膜在吹胀后的逆像与接近例外位的膜集合可以生成吹胀后的 Fukaya 分类。这一结果是对 Bayer 关于量子上同调结果的分类,并且是更一般猜想描述最小模型程序中过渡行为的一个例子,即 mmp 转换会生成额外的分解项。

英文摘要:

We compute the Fukaya category of the symplectic blowup of a compact rational symplectic manifold at a point in the following sense: Suppose a collection of Lagrangian branes satisfy Abouzaid's criterion for split-generation of a bulk-deformed Fukaya category of cleanly-intersecting Lagrangian branes. We show that for a small blow-up parameter, their inverse images in the blowup together with a collection of branes near the exceptional locus split-generate the Fukaya category of the blowup. This categorifies a result on quantum cohomology by Bayer and is an example of a more general conjectural description of the behavior of the Fukaya category under transitions occuring in the minimal model program, namely that mmp transitions generate additional summands.
