The Typical Structure of Sets With Small Sumset
- MathematicsInternational Mathematics Research Notices
- 2019
In this paper we determine the number and typical structure of sets of integers with bounded doubling. In particular, improving recent results of Green and Morris, and of Mazur, we show that the…

On the Bogolyubov–Ruzsa lemma
- Mathematics
- 2012
Our main result is that if A is a finite subset of an abelian group with |A+A| < K|A|, then 2A-2A contains an O(log^{O(1)} K)-dimensional coset progression M of size at least exp(-O(log^{O(1)} K))|A|.
LINEAR FORMS AND QUADRATIC UNIFORMITY FOR FUNCTIONS ON n p
- Mathematics
- 2011
We give improved bounds for our theorem in [W. T. Gowers and J. Wolf, The true complexity of a system of linear equations. Proc. London Math. Soc. (3) 100 (2010), 155–176], which shows that a system…
Set addition in boxes and the Freiman-Bilu theorem
- Mathematics
- 2005
We show that if A is a large subset of a box in Z^d with dimensions L_1 >= L_2 >= ... >= L_d which are all reasonably large, then |A + A| > 2^{d/48}|A|.
By combining this with Chang's quantitative…
On a question of Erdős and Moser
- Mathematics
- 2005
For two finite sets of real numbers A and B, one says that B is sum-free with respect to A if the sum set {b + b | b, b ∈ B, b 6= b} is disjoint from A. Forty years ago, Erdős and Moser posed the…

On Doubling and Volume: Chains
- Mathematics
- 2016
The well--known Freiman--Ruzsa Theorem provides a structural description of a set $A$ of integers with $|2A|\le c|A|$ as a subset of a $d$--dimensional arithmetic progression $P$ with $|P|\le c'|A|$,…
Finding Linear Patterns of Complexity One

We study the following generalization of Roth's theorem for 3-term arithmetic progressions. For s>1, define a nontrivial s-configuration to be a set of s(s+1)/2 integers consisting of s distinct…
Freiman's theorem in an arbitrary nilpotent group
- Mathematics
- 2012
We prove a Freiman–Ruzsa‐type theorem valid in an arbitrary nilpotent group. Specifically, we show that a K ‐approximate group A in an s ‐step nilpotent group G is contained in a coset nilprogression…
