- TL;DR Summary
- I am trying to understand the relation (significance) between the Lie groups such as so(3) and its Lie algebra?
I am just starting a QM course. I hope these are reasonable questions. I have been given my first assignment. I can answer the questions so far but I do not really understand what's going on. These questions are all about so(N) groups, Pauli matrices, Lie brackets, generators and their Lie algebra.
I am very confused about Lie groups and Lie algebras.
1. What is the difference (or connection) between them?
2. How do you get from a Lie group to a Lie algebra?
3. With regard to particle physics, what's so good about Lie algebra anyway?
