A finitely presented subgroup of the automorphism group of a right-angled Artin group
Published/Copyright:
November 1, 2012
Abstract.
Let 
be a right-angled Artin group. We use geometric methods to compute a presentation of the subgroup 
of 
consisting of the automorphisms that send each generator to a conjugate of itself. This generalizes a result of McCool on basis-conjugating automorphisms of free groups.
