Lueck's Approximation Theorem
Abstract: Last time we introduced L^2 homology and their Betti numbers. This time we prove the main theorem connecting
the classical and the L^2, namely Lueck's approximation theorem (realizing L^2 Betti numbers as an appropriate
limit of ordinary Betti numbers along a tower of covers).
