Abstract

Let GG be a group. We denote by ν(G)\nu(G) a certain extension of the non-abelian tensor square GGG \otimes G by G×GG \times G. We prove that if GG is a finitely generated group in which the set of all simple tensors T(G)T_{\otimes}(G) is finite, then the non-abelian tensor square GGG \otimes G and the group ν(G)\nu(G) are finite. Moreover, we show that if GG is a locally residually finite group in which the set of simple tensors T(H)T_{\otimes}(H) is finite for every proper finitely generated subgroup HH of GG, then the group ν(G)\nu(G) is locally finite.
