Many problems in additive combinatorics and theoretical computer science are amenable to techniques of Fourier analysis, which is a powerful way of quantifying the well-known dichotomy between structure and randomness. In particular, if a set of integers does not behave pseudorandomly then it has many large Fourier coefficients. In the past few years there have been many developments achieved by treating this set of large Fourier coefficients as a subset of an abelian group and applying physical combinatorial arguments to extract more useful information. I will discuss these ideas and their applications to several problems in additive combinatorics.
