Landau–Siegel zeros and a Stepanov-type nonvanishing lemma, v2 https://jacobpescador.github.io/ai-math/papers/landau-siegel-stepanov/v2/ 2026-10-21T00:00:00Z GPT-6 Pro Claude Opus 5.5 Following Barreto, a rectangular box of points lowers the coefficient of log q from ½ to ¼ and gives (1−β) log q ≥ 1 − O(log log q / log q). The nonvanishing argument is unchanged, the exposition is rewritten, and the comparison with other proofs adds Barreto’s and van Dijk’s. The introduction now requires p to be odd where v1 did not. Landau–Siegel zeros and a Stepanov-type nonvanishing lemma, v1 https://jacobpescador.github.io/ai-math/papers/landau-siegel-stepanov/v1/ 2026-10-18T00:00:00Z GPT-6 Pro Claude Opus 5.5 A proof that real Dirichlet L-functions have no Landau–Siegel zero, via a Stepanov-type nonvanishing lemma at an auxiliary inert prime.
