Proof of Proposition 2.5 Appendix A. Some Euler products Appendix B. Some arithmetic sums References 3. The set Ψ1 Let ν(n) and υ(n) be given by respectively. It is easy to see that Lemma 3.1. Assume (A) holds. Then Proof. Let which has the Euler product representation For σ ≥ σ0 > 0, by checking the cases χ(p) = ±1 and χ(p) = 0 respectively, it can be seen that and the implied constant depending on σ0. Thus φ(s) is analytic for σ > 1/2 and it satisfies for σ ≥ σ1 > 1/2, the implied constant depending on σ1. The left side of (3.2) is Lemma 3.2. Assume (A) holds. Then we have Proof. As the situation is analogous to Lemma 3.1 we give a sketch only. It can be verified that the function is analytic for σ > 1/2 and it satisfies for σ ≥ σ1 > 1/2, the implies constant depending on σ1. Also, one can verify that This completes the proof. Lemma 3.3. For any s and any complex numbers c(n) we have and Proof. The first assertion follows by the orthogonality relation; the second assertion follows by the large sieve inequality. Let By (3.1) we may write By Cauchy’s inequality and the first assertion of Lemma 3.3 we obtain Thus we conclude Lemma 3.4. The inequality Write Assume that (A) holds. By Cauchy’s inequality, the second assertion of Lemma 3.2 and Lemma 3.1, Thus we conclude Lemma 3.5 Assume that (A) holds. The inequality Let Assume that (A) holds. By Cauchy’s inequality, the first assertion of Lemma 3.2 and Lemma 3.1, Thus we conclude Lemma 3.6. Assume that (A) holds. The inequality We are now in a position to give the definition of Ψ1: Let Ψ1 be the subset of Ψ such that ψ ∈ Ψ1 if and only if the inequalities (3.4), (3.5) and (3.6) simultaneously hold. Proposition 2.1 follows from Lemma 3.4, 3.5 and 3.6 immediately. This paper is available on arxiv under CC 4.0 license. Author: (1) Yitang Zhang. Author: Author: (1) Yitang Zhang.
