Forschungsseminar: Gruppen und Operatoralgebren

André Nies (University of Auckland)

We introduce t.d.l.c. groups and then study their algorithmic aspects. A useful tool is the meet groupoid, which is the natural groupoid on compact open cosets, enriched by the intersection operation. Joint work with A. Melnikov.
