摘要

In the present paper, the authors extend to the q-tensor square G circle times(q) G of a group G, q an odd positive integer, some structural results due to Blyth, Fumagalli and Morigi concerning the non-abelian tensor square G circle times G (q = 0). The results are applied to the computation of G circle times(q) G for finitely generated nilpotent groups G, specially for free nilpotent groups of finite rank. We also generalize to all q >= 0 results of Bacon regarding an upper bound to the minimal number of generators of the non-abelian tensor square G circle times G when G is a n-generator nilpotent group of class 2. We end by computing the q-tensor squares of the free n-generator nilpotent group of class 2, n >= 2. This shows that the above mentioned upper bound is also achieved for these groups when q > 1, q odd.
