Abstract: Abstract We use polyhedral product models to analyse the structure of the commutator subgroup of a right-angled Artin group. In particular, we provide a minimal set of generators for the commutator subgroup, consisting of special… read more here.

Abstract: Abstract Given a group G and an automorphism φ of G, two elements x , y ∈ G are said to be φ-conjugate if x = g y φ ( g ) − 1 for… read more here.

Abstract: We study the outer automorphism group $Out(A_\Gamma)$ of the right-angled Artin group (RAAG) $A_\Gamma$ with defining graph $\Gamma$. A relative automorphism group is the stabilizer of a set of subgroups up to conjugacy; we consider… read more here.
