1-homology of combable groups and 3-manifold groups

Research output: Contribution to journalArticlepeer-review


S. Gersten asked whether the reduced ℓ1-homology of a group of type ℱn vanishes in all dimensions up to n - 1. We prove this for combable groups and for the fundamental groups of closed 3-manifolds. This means that the ℓ1-homology in these cases can be interpreted as "an amount of non-linearity" for the isoperimetric functions.
