: Definitions of Lie algebras, ideals, homomorphisms, and solvability.
Jacobson takes a distinctively algebraic approach. Unlike Humphreys' Introduction to Lie Algebras , which focuses heavily on the geometry of root systems early on, Jacobson builds the theory through derivations and the Killing form. jacobson lie algebras pdf
