Abstract

For a Reinhardt domain Ω\Omega with the smooth boundary in Cm+1\mathbb{C}^{m+1} and a positive smooth measure μ\mu on the boundary of Ω\Omega, we consider the ensemble PNP_{N} of polynomials of degree NN with the Gaussian probability measure γN\gamma_{N} which is induced by L2(Ω,dμ)L^{2}(\partial\Omega,d\mu). Our aim is to compute scaling limit distribution function and scaling limit pair correlation function between zeros when zΩz\in\partial\Omega. First of all we apply stationary phase method to the Boutet de Monvel-Sj\"{o}strand theorem to get the asymptotic for the partial szeg\"{o} kernel, SN(z,z)S_{N}(z,z), and then we compute the scaling limit partial szeg\"{o} 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.
