Lie Groups and Lie Algebras | Lecture 1

Convert to MP3 for your device with YouTube MP3jam
The first in a series of 4 lectures on Lie groups and Lie algebras (with a particular focus on physics) given by Gang Xu, a PSI Fellow, at the 2014-2015 PSI. This lecture provides an introduction to the subject, going through the motivation and basic examples/properties. If you're having trouble seeing the board at any point in the lectures, you can check out this pdf with snapshots of the board -- one shot for each change that occurs: These are NOT my videos! All rights, credit, etc. go to the Perimeter Institute, which can be found at the website linked to below. All the videos come from, and can be downloaded from in various formats and from previous years, the Perimeter Institute (where these lectures took place) website:
