Automorphism groups of free groups have many properties in common with automorphismÂ groups of free abelian groups, i.e., GL(n,Z).Â Interpolating between these are the automorphismÂ groups of right-angled Artin groups. In joint work with Karen Vogtmann, we have shown thatÂ many of these properties hold for all such groups. I will give an overview of our techniques and results.
