On the linearity of the holomorph group of a free group on two generators
F. R. Cohen, V. Metaftsis, S. Prassidis
Let F_n denote the free group generated by n letters. The purpose of this article is to show that Hol(F_2), the holomorph of the free group on two generators, is linear. Consequent…
Relatively free nilpotent torsion-free groups and their Lie algebras
C. Kofinas, V. Metaftsis, A. I. Papistas
For a torsion free finitely generated nilpotent group G we naturally associate four finite dimensional nilpotent Lie algebras over a field of characteristic zero. We show that if G…
On the residual finiteness of outer automorphisms of relatively hyperbolic groups
V. Metaftsis, M. Sykiotis
We show that every virtually torsion-free subgroup of the outer automorphism group of a conjugacy separable relatively hyperbolic group is residually finite. As a direct consequenc…
On the profinite topology of right-angled Artin groups
V. Metaftsis, E. Raptis
We give necessary and sufficient conditions on the graph of a right-angled Artin group that determine whether the group is subgroup separable or not. Moreover, we investigate the p…
