# Basic notions - Tamar Ziegler "Gower’s proof for 4-term arithmetic progressions in subsets of integers of positive density"

4:00pm to 5:00pm

Abstract: we give an overview of Gowers' proof for the existence of 4-term progression in subsets of positive density in the integers. We will discuss the tools from additive combinatorics that are used in the proof as well as some related conjectures.
