The Jamneshan-Tao conjecture for finite abelian groups of bounded rank
Pablo Candela, Diego González-Sánchez, Balázs Szegedy
We confirm the Jamneshan-Tao conjecture for finite abelian groups of rank at most a fixed integer (i.e. finite abelian groups generated by at most elements), by proving an…
An inverse theorem for all finite abelian groups via nilmanifolds
Pablo Candela, Diego González-Sánchez, Balázs Szegedy
We prove a first inverse theorem for Gowers norms on all finite abelian groups that uses only nilmanifolds (rather than possibly more general nilspaces). This makes progress toward…
On sets with missing differences in compact abelian groups
Pablo Candela, Fernando Chamizo, Antonio Córdoba
A much-studied problem posed by Motzkin asks to determine, given a finite set of integers, the so-called Motzkin density for , i.e., the supremum of upper densities of sets…
Free nilspaces, double-coset nilspaces, and Gowers norms
Pablo Candela, Diego González-Sánchez, Balázs Szegedy
Compact finite-rank nilspaces have become central in the nilspace approach to higher-order Fourier analysis, notably through their role in a general form of the inverse theorem for…
Spectral algorithms in higher-order Fourier analysis
Pablo Candela, Diego González-Sánchez, Balázs Szegedy
Our goal is to provide simple and practical algorithms in higher-order Fourier analysis which are based on spectral decompositions of operators. We propose a general framework for…
