  1. A final chapter shows, without proof, how to pass from Lie algebras to Lie groups (complex-and also compact). It is just an introduction, aimed at guiding the reader towards the topology of Lie groups and the theory of algebraic groups.

  2. The theme of this chapter is an investigation of complex semisimple Lie algebras by a two-step process, first by passing from such a Lie algebra to a reduced abstract root system via a choice of Cartan subalgebra and then by passing from the root system to an abstract Cartan matrix and an abstract Dynkin dagram via a choice of an ordering.

  3. The semisimple Lie algebras over the complex numbers were first classified by Wilhelm Killing (1888–90), though his proof lacked rigor. His proof was made rigorous by Élie Cartan (1894) in his Ph.D. thesis, who also classified semisimple real Lie algebras.

  4. An automorphism of the Lie algebra (g;[ ; ]) is a bijective endomorphism of Lie algebra of g. Exercise I.1.18 { Let (g;[ ; ]) and (h;[ ; ]) be Lie algebras, let f : g ! h be a morphism

  6. In this chapter, we begin the study of semisimple Lie algebras and their representations. This is one of the highest achievements of the theory of Lie algebras, which has numerous applications (for example, to physics), not to mention that it is also one of the most beautiful areas of mathematics.

  7. We shall now describe some of the general structure of any complex semi-simple Lie algebra. g. They depend on the existence of a large abelian Lie subalgebra, called the Cartan algebra.
