The Non-Abelian Tensor Square and Schur multiplier of Groups of Orders $p^2q$, $pq^2$ and $p^2qr$

Abstract

The aim of this paper is to determine the non-abelian tensor square and Schur multiplier of groups of square free order and of groups of orders $p^2q$, $pq^2$ and $p^2qr$, where $p$, $q$ and $r$ are primes and $p<q<r$.
