Sharp Fourier Extension on the Circle Under Arithmetic Constraints

Classical Analysis and ODEs 2024-02-15 v2 Number Theory

Abstract

We establish a sharp adjoint Fourier restriction inequality for the end-point Tomas-Stein restriction theorem on the circle under a certain arithmetic constraint on the support set of the Fourier coefficients of the given function. Such arithmetic constraint is a generalization of a B3B_3-set.
