Abstract

In this paper, we give necessary and sufficient conditions under which finite non-abelian metacyclic $p$-group ($p$ an odd prime) $G$ is capable. We also, determine the non-abelian tensor square $ G\otimes G$ for the groups of order $p^{\alpha+\beta}$ for some $\alpha, \beta\in \mathbb{N}$. Finally, we obtain some conditions on the parameters of two prime power groups $G_p$ and $G_q$ in which the groups have isomorphic non-commuting graphs.
