Additive combinatorics is a relatively recent term coined to comprehend
the developments of the more classical additive number theory, mainly
focussed on problems related to the addition of integers. Some classical
problems like the Waring problem on the sum of k-th powers or the
Goldbach conjecture are genuine examples of the original questions
addressed in the area. One of the features of contemporary additive
combinatorics is the interplay of a great variety of mathematical
techniques, including combinatorics, harmonic analysis, convex geometry,
graph theory, probability theory, algebraic geometry or ergodic theory.
This book gathers the contributions of many of the leading researchers
in the area and is divided into three parts. The two first parts
correspond to the material of the main courses delivered, Additive
combinatorics and non-unique factorizations, by Alfred Geroldinger, and
Sumsets and structure, by Imre Z. Ruzsa. The third part collects the
notes of most of the seminars which accompanied the main courses, and
which cover a reasonably large part of the methods, techniques and
problems of contemporary additive combinatorics.
