| dc.description | We consider polynomials on the unit circle defined by the recurrence relation Φ_{k+1}(z) = z Φ_{k} (z) - \barα_{k} Φ_k^{*}(z) for k \geq 0 and Φ_0=1. For each n we take α_0, α_1, ...,α_{n-2} i.i.d. random variables distributed uniformly in a disk of radius r < 1 and α_{n-1} another random variable independent of the previous ones and distributed uniformly on the unit circle. The previous recurrence relation gives a sequence of random paraorthogonal polynomials \{Φ_n\}_{n \geq 0}. For any n, the zeros of Φ_n are n random points on the unit circle. We prove that, for any point p on the unit circle, the distribution of the zeros of Φ_n in intervals of size O(1/n) near p is the same as the distribution of n independent random points uniformly distributed on the unit circle (i.e., Poisson). This means that, for large n, there is no local correlation between the zeros of the considered random paraorthogonal polynomials. | |
