Quotient groups of IA-automorphisms of free metabelian groups

C. E. Kofinas, A. I. Papistas

For a positive integer $n$ , with $n \geq 2$ , let $M_{n}$ be a free metabelian group of rank $n$ . For $c \in N$ , let $γ_{c} (M_{n})$ be the $c$ -th term of the lower central series…

IA-automorphisms and Lie Algebras related to the McCool group

C. E. Kofinas, V. Metaftsis, A. I. Papistas

In the present work we investigate a subgroup $I_{n}$ of the McCool group $M_{n}$ . We show that $I_{n}$ has solvable conjugacy problem. Next, we investigate its Lie Algebra gr( $I_{n}$ ) and…

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…
