指标定理中的路径积分方法

Path Integral Methods in Index Theorems

Mark van Loon

摘要:

本文提供了一个教学介绍量子力学路径积分和它的使用证明几何指标定理,特别是高斯-邦纳-陈定理和莱夫谢茨不动点定理。同时也涉及到数学物理中的一些重要概念,如定态相、超对称性和定域性等。它是针对高年级本科生和开始研究生,没有以前的知识超出本科量子力学假设。必要的数学背景在微分几何审查,虽然熟悉这种材料无疑是有帮助的。

英文摘要:

This paper provides a pedagogical introduction to the quantum mechanical path integral and its use in proving index theorems in geometry, specifically the Gauss-Bonnet-Chern theorem and Lefschetz fixed point theorem. It also touches on some other important concepts in mathematical physics, such as that of stationary phase, supersymmetry and localization. It is aimed at advanced undergraduates and beginning graduates, with no previous knowledge beyond undergraduate quantum mechanics assumed. The necessary mathematical background in differential geometry is reviewed, though a familiarity with this material is undoubtedly helpful.
