随机多项式的零点和临界点的极限经验分布一般是一致的

Limiting empirical distribution of zeros and critical points of random polynomials agree in general

Tulasi Ram Reddy

摘要:

本文研究了随机多项式的临界点(导数的零点)。取两个极限经验测度相同的复数确定性序列$\{a_n\}_{n\geq1}$和$\{b_n\}_{n\geq1}$。通过以相等概率选择$ξ_n = a_n$或$b_n$,由$P_n(z)=(z-ξ_1)\dots(z-ξ_n)$定义多项式序列。我们证明了在一定的假设下,该随机多项式序列的零点和临界点的极限测度是一致的。我们还证明了一个类似的结果三角数组的号码。对于广义导数(可认为是随机有理函数)的零点也证明了类似的结果。Pemantle和Rivin开创了随机多项式临界点的研究。Kabluchko证明了考虑零是独立同分布的结果。随机变量。

英文摘要:

In this article, we study critical points (zeros of derivative) of random polynomials. Take two deterministic sequences $\{a_n\}_{n\geq1}$ and $\{b_n\}_{n\geq1}$ of complex numbers whose limiting empirical measures are same. By choosing $ξ_n = a_n$ or $b_n$ with equal probability, define the sequence of polynomials by $P_n(z)=(z-ξ_1)\dots(z-ξ_n)$. We show that the limiting measure of zeros and critical points agree for this sequence of random polynomials under some assumption. We also prove a similar result for triangular array of numbers. A similar result for zeros of generalized derivative (can be thought as random rational function) is also proved. Pemantle and Rivin initiated the study of critical points of random polynomials. Kabluchko proved the result considering the zeros to be i.i.d. random variables.
