Abstract

Let χ\chi be a non-principal Dirichlet character modulo a prime pp. Let q1<q2q_1<q_2 denote the two smallest prime non-residues of χ\chi. We give explicit upper bounds on q2q_2 that improve upon all known results. We also provide a good upper estimate on the product q1q2q_1 q_2 which has an upcoming application to the study of norm-Euclidean Galois fields.
