An algorithm for higher-order Fourier analysis (joint work with P. Candela and B. Szegedy)
14 novembre 2024 @ 14:30 – 15:30 – Decomposing functions in terms of higher-order harmonics is a central topic in higher-order Fourier analysis. In its simplest form, such a decomposition is as follows. For a bounded function defined on a finite abelian group $f: Z\to \mathbb{C}$, we write it as $f=f_s+f_r+f_e$ where: $f_s$ is the sum of « a few » Fourier characters with large […]
