Automorphisms of Right-Angled Coxeter Groups
If (𝑊,𝑆) is a right-angled Coxeter system, then Aut(𝑊) is a semidirect product of the group Aut∘(𝑊) of symmetric automorphisms by the automorphism group of a certain groupoid. We show that, under mild conditions, Aut∘(𝑊) is a semidirect product of Inn(𝑊) by the quotient Out∘(𝑊)=Aut∘(𝑊)/Inn(𝑊). We al...
