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

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).
