局部化与镜像对称

Localization and Mirror Symmetry

Dustin Ross

摘要:

这些笔记是在2018年5月的雪鸟研讨会上为研究生举办的五个小时的系列讲座中诞生的。在等变上同调和局部化的简短入门之后,我们首先在Fan-Jarvis-Ruan-Witten理论中,然后在Gromov-Witten理论中证明了五次三重格的亏格零镜像定理。我们不要求原创性,除了在博览会,特别强调剥离标准的技术机械和查看镜像定理作为封闭式的表现形式的基本本地化递归。

英文摘要:

These notes were born out of a five-hour lecture series for graduate students at the May 2018 Snowbird workshop Crossing the Walls in Enumerative Geometry. After a short primer on equivariant cohomology and localization, we provide proofs of the genus-zero mirror theorems for the quintic threefold, first in Fan-Jarvis-Ruan-Witten theory and then in Gromov-Witten theory. We make no claim to originality, except in exposition, where special emphasis is placed on peeling away the standard technical machinery and viewing the mirror theorems as closed-formula manifestations of elementary localization recursions.
