Conditional upper bounds on the least character non-residue

  • Aritro Pathak

摘要

We extend known methods to establish upper bounds on the least character non-residues contingent on different zero-free regions within the critical strip, in particular on bounded rectangles within the critical strip along the \(\sigma =1\) σ = 1 line at arbitrary heights. This relates to earlier conditional results on least character non-residues, and recent results of Granville and Soundararajan, on character sums.
