L²-invariants seminar pre-meeting

  • Date:

    31.07.2025

  • Speaker:

    Roman Sauer

  • Time:

    13:00 Uhr

  • 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.  


    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.
