Roots of a Compact Lie Group by Kristopher Tapp
Publisher: arXiv 2009
Number of pages: 39
This expository article introduces the topic of roots in a compact Lie group. Compared to the many other treatments of this standard topic, I intended for mine to be relatively elementary, example-driven, and free of unnecessary abstractions. Some familiarity with matrix groups and with maximal tori is assumed.
