# Erdmann and Wildon Lie Algebras Ch5

2018-07-27

Erdmann and Wildon’s *Introduction to Lie Algebras* covers eigenvalues, weights, and the Invariance Lemma.

Most of this information is inspired from Linear Algebra, and the topics of eigenvalues vs weights were rather confusing (in terms of a linear algebra background). However, the introduction of the Invariance Lemma (when applied to the broad range of Lie Algebras) was rather interesting. Below are my notes:
