Overview

Abstract

We give a complete rational reconstruction of an explicit obstruction to positive definiteness for a fixed-center product of the Riemann theta density. At s₀ = ¼ log(13/(4π)), the signed derivative functional evaluated on the square of P(X) = X⁵ − 264X³ + 10952X lies in the exact rational interval [−1412370791.837791749, −1412370791.837791748]. The proof constructs derivatives by formal power series, retains twelve theta summands, bounds the entire remaining series, and encloses exponentials by range-reduced alternating series. A printed table of rational moment intervals proves the negative contraction. The odd derivative Hankel block is indefinite, and the six-point translation Gram has a negative direction at every sufficiently small positive spacing.

Scope of the work

This companion independently reconstructs the fixed-center obstruction in the original edition: https://luminaryoddities.com/researcharchive/explicit-quintic-obstruction-riemann-theta-kernel . It does not determine positive definiteness after averaging over the center, identify the smallest possible polynomial degree of failure, give an explicit numerical spacing for the six-point consequence, or resolve the Riemann Hypothesis. The original publication and its edition 1 remain unchanged.

Reproduction notes

The complete publication package contains main.tex and its required proof.tex, the PDF, a Python-standard-library verifier, certificate.json, moment_table.json, and checksum manifest. A fresh local run reconstructed the intervals and matched the retained certificate. Download the complete package to reproduce all dependencies.
