boundopen_question
Erdős Problem #510 remains OPEN. Statement: **Chowla's cosine problem** If $A\subset \mathbb{N}$ is a finite set of positive integers of size $N > 0$ then is there some absolute constant $c>0$ and $\theta$ such that $$\sum_{n\in A}\cos(n\theta) < -cN^{1/2}?$$ Topics: analysis. Erdős prize: no. Statement is machine-verified in Lean (formal-conjectures). OEIS: N/A.
