Rigidity of the Torelli subgroup in $O u t (F_{N})$

Sebastian Hensel, Camille Horbez, Richard D. Wade

Let $N$ be at least 4. We prove that every injective homomorphism from the Torelli subgroup into $O u t (F_{N})$ differs from the inclusion by a conjugation in $O u t (F_{N})$ . This applies…

Commensurations of subgroups of $Out (F_{N})$

Camille Horbez, Richard D. Wade

A theorem of Farb and Handel asserts that for $N \geq 4$ , the natural inclusion from $Out (F_{N})$ into its abstract commensurator is an isomorphism. We give a new proof of the…

Boundaries of relative factor graphs and subgroup classification for automorphisms of free products

Vincent Guirardel, Camille Horbez

Given a countable group $G$ splitting as a free product $G = G_{1} * \dots * G_{k} * F_{N}$ , we establish classification results for subgroups of the group $O u t (G, F)$ of all…
