L^2 Homology of Groups and Consequences - Lecture 2

Explore the intricacies of l^2 homology of groups in this 53-minute lecture from the Workshop on Geometry of Subgroups. Delve into the computation of various examples of l^2 homology groups, building upon the foundation laid in the previous session. Examine the consequences of these invariants, particularly when they vanish, and their significance for group theorists. Gain valuable insights into this advanced mathematical topic as presented by Robert Kropholler at the Centre de recherches mathématiques (CRM). This lecture is part of a comprehensive workshop series, offering a deep dive into the geometric aspects of subgroups in mathematics.
