|Title:||Additive combinatorics, Diophantine problems and Fourier analysis|
Fourier analysis has proved a fundamental tool in analytic and combinatorial number theory, usually in the guise of the Hardy–Littlewood circle method. When applicable, this method allows one to asymptotically estimate the number of solutions to a given Diophantine equation with variables constrained to a given finite set of integers. I will survey recent work extending the range of applicability of Fourier methods, with a focus on nonlinear problems in additive combinatorics.
