Semisimple and nilpotent orbits in semisimple Lie algebras

The Jordan Normal form gives a parametrization of the similarity classes of matrices. In particular, there are only finitely many similarity classes of nilpotent matrices and infinitely many for diagonal matrices. This concept will be generalised to any semisimple Lie algebra. The seminar deals with the classification of nilpotent and semisimple orbits and their description from a combinatorial, topological and symplectic geometry point of view.

The talks (more details and references)


Please contact me via email if you have any questions concerning your talk.

Here are basic rules which you should keep in mind:

  • Start to prepare your talk well in advance

  • The talk should be between 60 and 90 minutes

  • Things you should think of during the preparation of the talk:

What is the main result you want to present?

Which definitions and small lemmas are needed to formulate and prove it? Which results do you want to show with complete proof?

Is it maybe better to give the rough idea or important steps only?

Are there any nice examples which would help to understand the problem?

  • Come and see me or Olaf Schnuerer latest 2 weeks before the talk

  • Don't hesitate to contact me if you have any problems
