課程概述

The course basicaly follows the book “Additice Combinatorics” edited by Granville et al. [1], using Tao and Vu’s book [2] as an important addition. It will start at the classical theorem of arithmetic progressions by van der Waerden, and try to end at Szemeredi’s theorem, at least for the case of k = 3. Various tools as well as related topics will also be touched.  

課程目標
Additive combinatorics is currently a highly active area of resaerch for several reasons, for example its many applications to additive number theory. One remarkable feature of the field is the use of tools from many diverse fields of mathematics, including elementary combinatorics, harmonic analysis, convex geometry, incidence geometry, graph theory, probability, algebraic geometry, and ergodic theory; this wealth of perspectives makes addivitive combinatorics a rich, fascinating, and multi-faceted subject. The purpose of this course is to introduce basic tools in this subject.
