Abstract

LetG andG φ be isomorphic groups. We introduce and study a quotient ν(G) of the free productG *G φ which is a group extention of the non-abelian tensor squareGG. This seems to bring computational advantages to calculate this last group. Looking over ν as an operator in the class of groups we prove that it preserves properties of the argumentG such as finiteness, set of prime divisors, nilpotency and solvability. For a finitep-groupG we find a good polynomial bound for the order of ν (G).
