Nielsen realisation for untwisted automorphisms of right-angled Artin groups
We prove Nielsen realisation for finite subgroups of the groups of untwisted outer automorphisms of RAAGs in the following sense: given any graph $\Gamma$, and any finite group $G\leqslant \mathrm{U}^0(A_\Gamma) \leqslant \mathrm{Out}^0(A_\Gamma)$, we find a non-positively curved cube complex with f...
