Limit Groups of Equationally Noetherian Groups

Abstract: We collect in this paper some remarks and observations about limit groups of equationally noetherian groups. We show in particular, that some known properties of limit groups of a free group or, more generally, of a torsion-free hyperbolic group can be seen as consequences of the fact that such groups are equationally noetherian. Especially, such properties are still true for linear groups and finitely generated abelian-by-nilpotent groups.

“…Conversely if G is approximable by C, then G is locally fully residually-C. The same property holds also in hyperbolic groups [47,40] and more generally in equationally noetherian groups [36]. (3) Let V be a possibly infinite-dimensional vector space over a field K. Denote by GL(V, K) the group of automorphisms of V .…”

“…This coarser relation between G and H is an equivalent form of a definition due to Sela [56] that H is a G-limit group; see also [49]. A group A is a G-limit group if and only there exists a group containing A and preformed by G; see the remark after Lemma 2.18.…”

“…Baumslag, Myasnikov and Remeslinnikov show in [13,Thm B1] that all linear groups are equationally noetherian. Ould Houcine proves in [49] that, if G is equationally noetherian, then there are at most countably many groups that are limits of G, in particular, there are at most countably many groups preformed by G.…”

“…In this context, Γ-limit groups are precisely finitely generated fully residually-Γ groups, when the group Γ is either hyperbolic, as was shown by Sela in [Sel09] for the torsion-free case and by Reinfeldt and Weidmann in [RW10] for all hyperbolic groups, or Γ ∈ R, as was proved by Groves in [Gro05]. Yet more generally, the same result holds if Γ is an equationally Noetherian group, as was proved by Ould Houcine in [Hou07].…”
