This course is a one-semester introduction to Lie groups and their Lie algebras. In addition, I will devote some time to algebraic groups and Hopf algebras, in preparation for Reshetikhin's covering quantum groups in 261B in the Spring.

Prerequisites: Background in algebra and topology equivalent to 202A and 250A. Although 214 (Differential Manifolds) is the official prerequisite, I will review in the lectures those bits of differential geometry that we will need.


Planned syllabus:

  1. Definition and elementary properties of real and complex Lie groups
  2. Closed subgroups of GLn, classical Lie groups
  3. Lie algebra of a Lie group, exponential map
  4. Universal enveloping algebra, Poincaré-Birkhoff-Witt theorem
  5. Baker-Campbell-Hausdorff formula
  6. Homomorphisms, covering groups, Chevalley's theorem on Lie subgroups, Lie algebra-Lie group correspondence
  7. General structure theory of Lie algebras: solvable, nilpotent and semisimple Lie algebras, Lie and Engels' theorems, Cartan's criterion
  8. Ext groups of Lie algebra representations, theorems of Weyl, Levi and Ado, proof of the Lie algebra-Lie group correspondence completed.
  9. Representation theory of sl2
  10. Classification of complex semisimple Lie algebras
  11. Finite dimensional representations of semisimple Lie groups and algebras
  12. Compact Lie groups and semisimple complex Lie groups
  13. Algebraic groups, Hopf algebras
