素局部化的 Weinstein 子域

Prime-localized Weinstein subdomains

Oleg Lazarev, Zachary Sylvan

AI总结:

本文提出一种构造方法,针对高维 Weinstein 域和素数集合生成其 wrapped Fukaya category 的素局部化子域,并分类了单连通自旋流形余切丛子域的可能范畴,同时揭示了球面余切丛中同构于真实 Lagrangians 的 twisted complexes。

摘要:

对于任意高维 Weinstein 域和素数的有限集合,我们构造了一个 Weinstein 子域,其 wrapped Fukaya category 是原 wrapped Fukaya category 在给定素数处的局部化。当原域是余切丛时,这些子域构成一个递减格,其顺序不可逆。此外,我们分类了单连通、自旋流形的余切丛的 Weinstein 子域的可能 wrapped Fukaya categories,证明它们均与这些素局部化之一重合。在此过程中,我们描述了球面余切丛的 wrapped Fukaya category 中的哪些 twisted complexes 同构于真实 Lagrangians。

英文摘要:

For any high-dimensional Weinstein domain and finite collection of primes, we construct a Weinstein subdomain whose wrapped Fukaya category is a localization of the original wrapped Fukaya category away from the given primes. When the original domain is a cotangent bundle, these subdomains form a decreasing lattice whose order cannot be reversed. Furthermore, we classify the possible wrapped Fukaya categories of Weinstein subdomains of a cotangent bundle of a simply connected, spin manifold, showing that they all coincide with one of these prime localizations. In the process, we describe which twisted complexes in the wrapped Fukaya category of a cotangent bundle of a sphere are isomorphic to genuine Lagrangians.
