From Betti numbers to l2-Betti numbers

오버불파크에서 찍은 현대수학의 면모

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.
