Abstract

A theorem of Folner asserts that for any set A subset of Z of positive upper density there is a Bohr neigbourhood B of 0 such that B \ (Lambda - Lambda) has zero density. We use this result to deduce some consequences about the structure of difference sets of sets of integers having a positive upper density.
