On the optimal constant in the Montgomery-Vaughan weighted Hilbert inequality

Brad Rodgers

Abstract

We give a proof that the optimal constant in the weighted Hilbert inequality is strictly greater than $π$, answering in the negative a question asked by Montgomery and Vaughan. The proof proceeds via an explicit limiting counterexample.

These began in 2024 but it was only recently that programs written by ChatGPT 5.6 Sol uncovered unexpected high-dimensional behavior. A further back and forth about these numerics led ultimately to the proof of Theorem 1.1 given in Section 2. The proof that appears here is a modification and simplification of a proo”
