For a finitely generated group $G$, we study deformation spaces of metric $G$-trees, which are analogues of the Teichmüller spaces of surfaces for group actions on trees. Deformation spaces of metric $G$-trees generalize Culler- Vogtmann's Outer space, the deformation space of free actions on trees, which has proven to be immensely useful in the study of $Out(F_n)$, the outer automorphism group of the free group of rank $n\geq 2$. Let $\mathcal{D}$ be a deformation space of metric $G$-trees. The group of positive real numbers $\mathbb{R}_{>0}$ acts on $\mathcal{D}$ by scaling the metrics on the trees and we define the projectivized deformation space as the quotient $\mathcal{PD}=\mathcal{D}/\mathbb{R}_{>0}$. The outer automorphism group $Ou...
