We consider “graph-groups”, i. e. groups given by genetic codes, containing only commutativity relations for certain pairs of generators. The image of the automorphism group of a graph-group under abelianization map is described.
Keywords: graph group, link digraph, algebraic $\mathbb Q$-group, Levy decomposition, reductive group, arithmetic group, Kazhdan's property $(T)$, Serre's property $(FA)$
Mots-clés : unipotent radical, automorphism group.
