Sodin's moderate and large deviation conjecture for planar GAF zeros

At least 19 years old · documented by

Let n(r)n(r) be the number of zeros of the planar Gaussian analytic function g\mathbf g in the disk D(0,r)D(0,r). Sodin's deviation conjecture. As r→∞r\to\infty,

log⁡log⁡(1P[∣n(r)−r2∣>rα])log⁡r⟶{2α−1,12≤α≤1,3α−2,1≤α≤2,2α,2≤α.\genfrac{}{}{}{}{\log\log\left(\genfrac{}{}{}{}{1}{{\bf P}[|n(r)-r^2|>r^\alpha]}\right)}{\log r}\longrightarrow \begin{cases} 2\alpha-1,&\genfrac{}{}{}{}{1}{2}\leq\alpha\leq 1,\\ 3\alpha-2,&1\leq\alpha\leq 2,\\ 2\alpha,&2\leq\alpha. \end{cases}

This predicts the logarithmic scale of deviations of the zero count across moderate and very large deviation regimes; the source presents it as a conjecture inspired by physical results for Coulomb gases.
