Universality conjecture for the microscopic roots of random polynomials

At least 5 years old · documented by

Let fn(z)=∑j=0nεjzjf_n(z)=\sum_{j=0}^n\varepsilon_j z^j, where {εj}j\{\varepsilon_j\}_j are iid real random variables satisfying E ε1=0\mathbb{E}\,\varepsilon_1=0 and E ε12=1\mathbb{E}\,\varepsilon_1^2=1. Universality conjecture. The conclusion of Theorem 1.1 still holds: the rescaled zero set {(∣ζ∣−1)n2:fn(ζ)=0}\{(|\zeta|-1)n^2:f_n(\zeta)=0\} converges, as n→∞n\to\infty, to a homogeneous Poisson process with intensity 1/121/12, in the vague topology. This is proposed as a target for future research and is not proved in the paper.
