Abelian Subgroup Separability of Certain Generalized Free Products of Groups
Keyword(s):
We prove that generalized free products of certain abelian subgroup separable groups are abelian subgroup separable. Applying this, we show that tree products of polycyclic-by-finite groups, amalgamating central subgroups or retracts are abelian subgroup separable.
