Présentiel

We give an introduction to L2-homology and L2-Betti numbers which generalizes the well-known classical notions of homology and Betti numbers. They have suprising applications to problems in topology, geometry, and group theory which a priori seem not be related, but whose proofs require
L2-techniques. We also discuss some open conjectures.
