Enumeration of three term arithmetic progressions in fixed density sets [PDF]

, 2014
Additive combinatorics is built around the famous theorem by Szemer\'edi which asserts existence of arithmetic progressions of any length among the integers. There exist several different proofs of the theorem based on very different techniques.
