Zeroes of random Reinhardt polynomials

preprint2014arXivOpen access

Abstract

For a Reinhardt domain ΩΩ with the smooth boundary in Cm+1\mathbb{C}^{m+1} and a positive smooth measure μμ on the boundary of ΩΩ, we consider the ensemble PNP_{N} of polynomials of degree NN with the Gaussian probability measure γNγ_{N} which is induced by L2(∂Ω,dμ)L^{2}(\partialΩ,dμ). Our aim is to compute scaling limit distribution function and scaling limit pair correlation function between zeros when z∈∂Ωz\in\partialΩ. First of all we apply stationary phase method to the Boutet de Monvel-Sjöstrand theorem to get the asymptotic for the partial szegö kernel, SN(z,z)S_{N}(z,z), and then we compute the scaling limit partial szegö kernel in any direction in Cm+1\mathbb{C}^{m+1}, then by using well-known Kac-Rice formula we compute scaling limit distribution function and scaling limit pair correlation function between zeros.
