Abstract:

We extend a result due to Bourgain on the uniform distribution of residues by proving that subsets of the type $f(I)\cdot H$ are equidistributed (as $p$ tends to infinity), where $f$ is a polynomial, $I$ is an interval of $\mathbb {F}_p$ and $H$ is an approximate subgroup of $\mathbb {F}_p^*$ with size larger than polylogarithmic in $p$.
