Slides of the talk

Introduction and survey on L2-invariants

Abstract:  We present an  introduction to L2-Betti numbers including their basic properties, main immediate applications and a status report. We discuss open prominent problems. If time allows, we will also treat L2-torsion, a much more sophisticated invariant.

The talk  is for non-experts and shall shed light on the forthcoming thematic program about L2-invariants
