Automorphisms of two-dimensional RAAGs and partially symmetric automorphisms of free groups

Kai-Uwe Bux, Ruth Charney, Karen Vogtmann

We compute the virtual cohomological dimension (VCD) of the group of partially symmetric outer automorphisms of a free group. We use this to obtain new upper and lower bounds on th…
