THE RESONANCE METHOD FOR LARGE CHARACTER SUMS
Published online by Cambridge University Press: 11 September 2012
Abstract
We consider the size of large character sums, proving new lower bounds for Δ(N,q)=sup χ≠χ0 mod q∣∑ n<Nχ(n)∣ in almost all ranges of N. The proofs use the resonance method and saddle point analysis.
