Abstract

Integrating out supersymmetric M2 branes wrapped on two-cycles in Calabi–Yau manifolds is an important calculation: it allows the determination of, and in some ways defines, the free energy of topological strings. In these notes, based on a short course aimed at graduate students, we go through various aspects of this calculation in detail. The end result is a recently proposed new formula for the topological string free energy.

关于M2膜积分的注意事项

对Calabi-Yau流形中包裹在两个环上的超对称M2膜进行积分是一个重要的计算：它允许确定，并在某种程度上定义拓扑弦的自由能。在这些笔记中，基于一门针对研究生的短期课程，我们将详细介绍这种计算的各个方面。最终的结果是最近提出的拓扑弦自由能的新公式。
