几何(Clifford)代数及其应用

Geometric (Clifford) algebra and its applications

Douglas Lundholm

摘要:

在这篇理学硕士论文中,我从向量空间的传统几何设置以及简化常见关系和操作的组合观点介绍几何代数。这一观点使我们能够定义Clifford代数与标量在任意环,并提供了新的建议,无限维的方法。此外,我给出了一个快速审查的经典结果几何代数,如他们的分类矩阵代数,连接到正交和自旋群,和他们的表示论。一些低维的例子,制定了一个系统的方式使用所谓的范数函数,而一般的应用表示论包括赋范除法代数和向量场的领域。我也考虑在相对论物理学的例子,在几何代数方面的重新制定引起计算和概念简化。

英文摘要:

In this Master of Science Thesis I introduce geometric algebra both from the traditional geometric setting of vector spaces, and also from a more combinatorial view which simplifies common relations and operations. This view enables us to define Clifford algebras with scalars in arbitrary rings and provides new suggestions for an infinite-dimensional approach. Furthermore, I give a quick review of classic results regarding geometric algebras, such as their classification in terms of matrix algebras, the connection to orthogonal and Spin groups, and their representation theory. A number of lower-dimensional examples are worked out in a systematic way using so called norm functions, while general applications of representation theory include normed division algebras and vector fields on spheres. I also consider examples in relativistic physics, where reformulations in terms of geometric algebra give rise to both computational and conceptual simplifications.
