On the volume set of point sets in vector spaces over finite fields

Abstract

We show that if $\mathcal{E}$ is a subset of the $d$-dimensional vector space over a finite field $\mathbbm{F}_q$ ($d\ge 3$) of cardinality $|\mathcal{E}|\ge (d-1)q^{d-1}$, then the set of volumes of $d$-dimensional parallelepipeds determined by $\mathcal{E}$ covers $\mathbbm{F}_q$. This bound is sharp up to a factor of $(d-1)$ as taking $\mathcal{E}$ to be a $(d-1)$-hyperplane through the origin shows.
