In this paper we give an example of a linear group such that its tensor square is not linear. Also, we formulate some sufficient conditions for the linearity of non-abelian tensor products GHG \otimes H and tensor squares GGG \otimes G. Using these results we prove that tensor squares of some groups with one relation a…
