Abstract:
We look at Baumslag–Solitar groups. Lower central series are given for residually nilpotent Baumslag–Solitar groups. For some Baumslag–Solitar groups that are not residually nilpotent, we find the intersection of all terms of the lower central series. Also we point out non-Abelian Baumslag–Solitar groups having lower central series of length 2. For some Baumslag–Solitar groups, a relationship is established between an intersection of subgroups of finite index and an intersection of terms of the lower central series.
Keywords:
Baumslag–Solitar groups, residual nilpotency, lower central series.
