Abstract
Let G, H be groups that act compatibly on each other and consider the non-abelian tensor product \(G \otimes H\). We prove that the set of all tensors \(T_{\otimes }(G,H)=\{g\otimes h{:}\,g \in G,\,h\in H\}\) is finite if and only if the non-abelian tensor product \(G \otimes H\) is finite. Further, we examine a finiteness criterion for \(G \otimes H\), when G and H are FC-groups. We also establish a sufficient condition for a finitely generated non-abelian tensor product to be finite. Some finiteness conditions for G in terms of certain torsion elements of the non-abelian tensor square \(G \otimes G\) are also studied.
