From Betti numbers to l2-Betti numbers

Instantanés de recherche mathématique à Oberwolfach

From Betti numbers to l2-Betti numbers

We provide a leisurely introduction to l2-Betti numbers, which are topological invariants, by relating them to their much older cousins, Betti numbers. In the end we present an open research problem about l2-Betti numbers.
