Understanding the problem

Read the background

For every eta > 0 and every sufficiently large integer N, there is a Littlewood polynomial with N consecutive coefficients in {−1,1} whose maximum modulus on the unit circle is at most (1+eta) sqrt(N).

Why it matters

If correct, proves that the minimum normalized maximum tends to one through all integer lengths, refuting the real-sign fixed-gap conjecture.

What counts as progress

Can real-sign Littlewood polynomials approach the Parseval minimum for maximum modulus at every sufficiently large length?
