Syllabus / reading materials

The goal of this course is to learn the fundamental ideas in representation theory. We first start from the unitary representations of finite groups to get the grasp of basic ideas. We then move to Lie groups and Lie algebras to handle continuous groups. The first main goal of this lecture is to explain the classification of simple Lie groups combining ideas from these. We then move to more advanced topics such as general compact groups (more general), symmetric groups and type A groups (more specialized)...

The topics include:

  1. Unitary representation of finite groups
    • complete reducibility
    • character theory
  2. Lie groups and Lie algebras
    • basic correspondence between Lie groups and Lie algebras
    • solvable vs. semisimpe Lie algebras
  3. Simple Lie groups
    • compact vs. complex Lie algebras
    • maximal torus and Cartan subalgebras
    • root system and Weyl group
    • Dynkin diagrams
    • highest weight theory
  4. Advanced topics: (some of)
    • general compact groups, Haar measure, Peter-Weyl theorem...
    • representation of symmetric groups, Schur-Weyl duality...
    • flag manifolds, Borel-Weil-Bott theorem...
    • induced representations, Mackey's criterion, Artin's theorem...
