Automorphism groups of Coxeter groups do not have Kazhdan's property (T)
Appears in collection : Virtual Geometric Group Theory conference / Rencontre virtuelle en géométrie des groupes
We show that for a large class $w$ of Coxeter groups the following holds : given a group $W_{\Gamma }$ in $W$, the automorphism group Aut($W_{\Gamma }$) does not satisfy Kazhdan's property (T).
