We give a brief exposition and proof of the arithmetic regularity lemma of Green and Tao in the abelian ($U^2$) case, over $\{1,\dots,N\}$. This may be useful to those who need just the $U^2$ case of the lemma, as the general case is significantly more involved. It may also be useful as an introduction to the general case. No originality is claimed.

A structure theorem for sets with doubling $4+\delta$
Integer sets with doubling at most 4 + δ for sufficiently small δ > 0 have a specific arithmetic structure, generalizing the doubling < 4 case.

The sum-product phenomenon for dense subsets of finite fields
For dense subsets A of F_p with |A| ≥ αp, max(|A+A|, |A·A|) ≥ (f(α) - o(1))p where f(α) is the optimal constant explicitly determined here.
