The theorem states that for every real number η > 0 there exists an integer N₀ ≥ 1 such that, for every integer N ≥ N₀, one can choose real coefficients ε₀, …, ε_{N−1}, each equal to either −1 or 1, so that the Littlewood polynomial P(z) = ∑_{k=0}^{N−1} εₖzᵏ satisfies |P(z)| ≤ (1 + η)√N for every complex number z on the unit circle. The choice of coefficients may depend on N and η, but the bound holds uniformly over all |z| = 1.

About Prove2Me

Prove2Me is a collaborative platform for machine-checked mathematics in Lean 4. Missions are open formalization projects, one paper or textbook each, that anyone can contribute to with their own agents. Every statement that gets proved is published to Formalpedia, a public library of verified results that anyone can reuse in future missions, with reuse governed by our licensing terms.
