  • Speaker:

    Roman Sauer

  • Seminar description: L2-invariants are invariants of spaces and groups whose definition has a both a functional-analytic and topological flavor. The purpose of this seminar is: 

    - to introduce the students to the modern algebraic approach to l2-invariants that minimizes the analysis. 

    - to explore applications of l2-invariants in (geometric) group theory. 

    - to discuss current research questions and conjectures around l2-invariants.  

     

    A draft of the schedule for the seminar program can be found here.


    Some knowledge of geometric group theory or algebraic topology or functional analysis (but not necessarily of all three subjects) is recommended. 

    The seminar will be held in English and as a “Blockseminar” at the start of the semester break in Februar.
