AB - We report on what we call the Hamidoune problem, inspired by a problem by Dicks and Ivanov. The problem asks if the inequality
holds when A and B are finite subsets of a group G, each one with at least two elements, and A·2B denotes the set of elements which can be written in at least two different ways as a product of one element in A and one in B.
