Given a finite simplicial graph G, the graph group GG is the group with generators in one-to-one correspondence with the vertices of G and with relations stating that two generators commute if their associated vertices are adjacent in G. The Bieri-Neumann-Strebel invariant can be explicitly described in terms of the original graph G and hence there is an explicit description of the distribution of finitely generated normal subgroups of GB with abelian quotient. We construct Eilenberg-MacLane spaces for graph groups and find partial extensions of this work to the higher-dimensional invariants.
