Relative automorphism groups of right-angled Artin groups
We study the outer automorphism group of a right‐angled Artin group AΓ with finite defining graph Γ . We construct a subnormal series for Out(AΓ) such that each consecutive quotient is either finite, free‐abelian, GL(n,ℤ) or a Fouxe‐Rabinovitch group. The last two types act, respectively, on...
