真实的根的数量一直是随机多项式和随机函数理论的中心课题,因为Littlewood-Offord和Kac在20世纪40年代的基本论文。本文建立了系数具有中等增长的随机多项式的真实的根个数的中心极限定理,推广和加强了Maslova的一个经典结果。
The number of real roots has been a central subject in the theory of random polynomials and random functions since the fundamental papers of Littlewood-Offord and Kac in the 1940s. In this paper, we establish the Central Limit Theorem for the number of real roots of random polynomials with coefficients having moderate growth, generalizing and strengthening a classical result of Maslova.
