Fourier optimization, the least quadratic non-residue, and the least prime in an arithmetic progression
Abstract
By means of a Fourier optimization framework, we improve the current asymptotic bounds under GRH for two classical problems in number theory: the problem of estimating the least quadratic non-residue modulo a prime, and the problem of estimating the least prime in an arithmetic progression.
