Symplectic geometry is the mathematical foundation for particle motion in classical physics. Recently, research in this area has centered on the study of quantum invariants defined using geometric objects known as holomorphic curves. These quantum invariants have appeared not only in fields of mathematics known as geometric analysis and low-dimensional topology but also in certain models in high-energy physics. The investigator will study the behavior of these quantum invariants under adiabatic limits in which directions in space or time are re-scaled. Applications will be of interest in topology and physics. The investigator will also continue his mentoring and outreach activities in mathematics education.The investigator will study three types of adiabatic limits of quantum invariants in symplectic geometry. First, he will study the limit of the Fukaya category of a symplectic manifold under the multi-directional symplectic field theory limit, which is equivalent in many cases to shrinking the fibers of a Lagrangian torus fibration. The investigator will extend previous results to Lagrangians compatible with this tropical limit and apply the results to examples arising in mirror symmetry, such as the computation of disk potentials. Secondly, the investigator will study the behavior of the Fukaya category and quantum cohomology under flips with non-trivial centers, or equivalently, mean curvature flow in which a subset of the symplectic manifold collapses over some non-trivial base, with the aim of constructing generators for the Fukaya category. A related project in gauge theory will study the behavior of higher rank monopole Floer homology under variation of monopole parameter, and relate these invariants with instanton homology and abelian monopole Floer homology. In a third project, the investigator will study the limits of flow spaces arising from Fukaya-isomorphic Lagrangians in cotangent bundles as the Lagrangians approach the zero section via rescaling, and in particular higher-dimensional moduli spaces of Morse flow trees that appear in the limit.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

辛几何是经典物理学中粒子运动的数学基础。最近，该领域的研究集中在使用称为全纯曲线的几何对象定义的量子不变量的研究上。这些量子不变量不仅出现在几何分析和低维拓扑等数学领域，而且还出现在高能物理的某些模型中。研究人员将研究这些量子不变量在绝热极限下的行为，其中空间或时间的方向被重新缩放。 应用领域包括拓扑学和物理学。研究人员还将继续他在数学教育方面的指导和推广活动。研究人员将研究辛几何中量子不变量的三种绝热极限。 首先，他将研究多向辛场论极限下辛流形的深谷范畴的极限，这在许多情况下相当于收缩拉格朗日环面纤维的纤维。 研究人员将把之前的结果扩展到与这个热带极限兼容的拉格朗日量，并将结果应用于镜像对称中出现的例子，例如圆盘势的计算。 其次，研究者将研究深谷范畴和量子上同调在非平凡中心翻转下的行为，或者等效地，辛流形子集在某个非平凡基上塌陷的平均曲率流，目的是构造Fukaya 类别的发电机。 规范理论中的一个相关项目将研究单极参数变化下高阶单极弗洛尔同调的行为，并将这些不变量与瞬时子同调和阿贝尔单极弗洛尔同调联系起来。 在第三个项目中，研究人员将研究当拉格朗日通过重新缩放接近零截面时，余切丛中的深谷同构拉格朗日所产生的流空间的极限，特别是出现在极限中的莫尔斯流树的高维模空间该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
