Multiplicativity of sets

Number theory

Expanding the known multiplicative properties of large difference sets yields a new, quantitative proof on the structure of product sets.

On some multiplicative properties of large difference sets

In our paper we study multiplicative properties of difference sets A−AA−A for large sets A⊆Z/qZA \subseteq \mathbb{Z}/q\mathbb{Z} in the case of composite qq. We obtain a quantitative version of a result of A. Fish about the structure of the product sets (A−A)(A−A)(A−A)(A−A). Also, we show that the multiplicative covering number of any difference set is always small.
