旋量结构的分类

Classifying Spinor Structures

Scott Morrison

摘要:

我首先解释如何黎曼几何可以理解的主要纤维丛和连接。然后,我介绍和激励旋量结构的定义在熟悉的几何思想。本论文的中心结果是旋量结构的一个完整的和建设性的分类,推广了一些早期的结果。我将解释主纤维丛和覆盖空间如何提供证明的关键成分。根据基本的主纤维丛,也可以尝试不同类型的分类,这使我们能够比较“旋量连接”。最后部分指出洛伦兹流形的旋量结构如何为“旋量演算”提供自然设置,从而为电子的狄拉克方程提供自然设置。研究了旋量结构的选择对狄拉克方程的影响。

英文摘要:

I begin by explaining how Riemannian geometry can be understood in terms of principal fibre bundles and connections thereon. I then introduce and motivate the definition of a spinor structure in terms of familiar geometrical ideas. The central result of this thesis is a complete and constructive classification of spinor structures, generalising some earlier results. I will explain how principal fibre bundles and covering spaces provide the key ingredients to the proof. A different type of classification can also be attempted, in terms of the underlying principal fibre bundle, and this allows us to compare `spinor connections'. The final part indicates how spinor structures for Lorentzian manifolds provide the natural setting for the `spinor calculus', and so for the Dirac equation for the electron. The effect of the choice of spinor structure on the Dirac equation is investigated.
