Finiteness Conditions for the $n$-fold Tensor Product of Groups

Abstract

Let $G$ be a finitely generated group. We prove that the $n$-fold tensor product $G^{\otimes n}$ is finite (resp. polycyclic) if and only $G$ is finite (resp. polycyclic). Further, assuming that $G$ is finitely presented, we show that $G^{\otimes n}$ is finitely presented if and only if ${\gamma }_n(G)$ is finitely presented. We also examine some finiteness conditions for the non-abelian tensor product of groups.
