Baumslag-Solitar groups and residual nilpotence

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

For a Baumslag-Solitar group $G$ we calculate the intersection ${\gamma }_w(G)$ of all terms of the lower central sequence of $G$.Using this we are able to show that $[{\gamma }_w(G),G]={\gamma }_w(G)$ th…
