A structure theorem for product sets in extra special groups

Number Theory 2018-08-28 v2 Combinatorics

Abstract

Hegyv\'ari and Hennecart showed that if BB is a sufficiently large brick of a Heisenberg group, then the product set BBB\cdot B contains many cosets of the center of the group. We give a new, robust proof of this theorem that extends to all extra special groups as well as to a large family of quasigroups.
