Weak Gotsman–Linial conjecture on polynomial threshold function influence

About 9 years old · traced to

Let f:{−1,1}n→{−1,1}f:\{-1,1\}^n\to\{-1,1\} be a degree-dd polynomial threshold function, and let I⁡[f]\operatorname{\mathbf{I}}[f] denote its total influence. Weak Gotsman–Linial conjecture. For any degree-dd threshold function ff on nn variables,

I⁡[f]≤O(dn).\operatorname{\mathbf{I}}[f]\le O(d\sqrt{n}).

This is a relaxation of the refuted exact Gotsman–Linial maximizer conjecture: for d<nd<\sqrt n, the conjectured symmetric bound has order Θ(dn)\Theta(d\sqrt n), and the weaker asymptotic upper bound remains the relevant question in the paper.

RemarkAI-assistedClaimed by OpenAI. For every polynomial threshold function on the uniform n-dimensional Boolean cube with 1 <= d <= n, the manuscript claims total influence, equivalently average sensitivity, at most 8dsqrt(n). This addresses the page’s weak Gotsman–Linial order bound. It does not assert the refuted exact symmetric-maximizer formulation or an optimal leading constant.See full solutionHide full solution
