Abstract :

  A manifold is L²-acyclic if its L²-Betti numbers vanish. One can ask when an L²-acyclic manifold is a boundary of an L²-acyclic manifold with the same fundamental group. We develop the geometric topology necessary to answer this question for manifolds of dimension greater than 4 and virtually abelian fundamental group.
