Work group Operator algebras and non-commutative geometry

Our work group represents the fields of operator algebras and noncommutative geometry in teaching and research. The current focus of our research is

  • structure of C * algebras and more general non-commutative algebras, in particular their K-theory and cyclic homology, as well as cohomology, group C * algebras
  • representation theory of locally compact groups and the Baum-Connes conjecture
  • non-commutative dynamic systems such as crossed products and ring C * algebras
  • quantized spaces
  • quantum groups and quantum groupoids


We meet every Monday 14 - 16 in SRZ 216 for kleines seminar that is addressed mainly to MSc and PhD students, and to PostDocs.

 

During the lecture period, we meet for talks at Oberseminar C* algebras every Tuesday at 15:45 with coffee, cake and time for discussions in the seminar room SRZ 216 (Orléans-Ring 12).
