Title: Quasipolynomial bounds on the inverse theorem for the Gowers norms and applications

Abstract: Recent work, joint with James Leng and Mehtaab Sawhney, improves the so-called “inverse theorem” for the Gowers $U^{s+1}[N]$-norm which arises in the field of additive combinatorics in relation to Roth’s and Szemerédi’s theorems. I will explain how the field of higher-order Fourier analysis broadly extends Fourier methods and the circle method in number theory, and discuss implications of bounds for inverse theorems.
