CAREER Aspects Microlocal Geometry

项目摘要

In modern mathematics, symplectic geometry is the abstract setting for classical mechanics, and microlocal analysis is a tool used to study solutions to systems of differential equations. Microlocal sheaf theory is the geometric formulation of microlocal analysis. Recent advances have uncovered striking applications of microlocal sheaf theory to symplectic geometry. This project will explore and extend these applications in various directions, including further developing algebraic and combinatorial connections between curves, knots, and surfaces. In terms of education, the principal investigator will prepare much-needed elementary expository works on the subject of microlocal sheaf theory.The specific research goals of the proposal are twofold. First, to localize the calculations of the Fukaya category of a Weinstein manifold (a certain sort of exact symplectic manifold) to its Lagrangian skeleton. Once localized, performing this calculation is a matter of combinatorics; thus secondly, the PI intends to explore the resulting combinatorics. It is already known that the sort of combinatorics that arises has a representation-theoretic flavor; in particular cluster algebras and categorified knot invariants appear. Further insights in these subjects will be gained by exploring their connection with symplectic geometry in terms of the above-mentioned skeleta. The localization and calculation of these Fukaya categories that are the focus of this research will play an essential role in an approach to the homological mirror symmetry conjecture.

在现代数学中，辛几何是经典力学的抽象背景，微局部分析是用于研究微分方程组的解的工具。微局部层理论是微局部分析的几何表述。最近的进展揭示了显着的应用微局部层理论辛几何。这个项目将探索和扩展这些应用在各个方向，包括进一步开发曲线，节点和曲面之间的代数和组合连接。在教育方面，主要研究者将准备急需的关于微观局部层理论的基础性著作。该提案的具体研究目标是双重的。首先，将Weinstein流形（一种精确辛流形）的福谷范畴的计算局部化到它的拉格朗日骨架上。一旦本地化，执行此计算是一个组合问题;因此，第二，PI打算探索由此产生的组合。我们已经知道，组合学的出现具有代表性理论的味道，特别是集群代数和分类结不变量出现。进一步的见解，在这些科目将获得通过探索他们的连接与辛几何在上述方面的EQUETA。这些福谷范畴的定位和计算是本研究的重点，将在同调镜像对称猜想的方法中发挥重要作用。
