Various

• Seminar 'Topics in Mathematical Physics' (link). Currently following the book by Liviu Nicolaescu on An invitation to Morse theory.
  
  Great opportunity for M.Sc. students that like to follow a more advanced course. This time in differential geometry, but also other topics can be treated in the sequel. Also suggestions are very welcome!
  
  
• Seminar 'Topics in operator algebras' (link). Finished with the topic subfactors.
  
  
• Course on Quantum Groups and Special Functions (Faculte des Sciences de Bizerte, Tunisia, 22-26 February 2010). Assistent for the exercise sessions. See Erik Koelink his page. The notes can be downloaded here.
