关于环R和环C上随机多项式的一些最新结果的评述

A review of some recent results on random polynomials over R and over C

Diego Armentano

摘要:

本文分为两个部分。第一部分回顾了随机多项式方程组实根期望数的一些最新结果。在第二部分中,我们处理一个不同的问题,即某些复杂的随机多项式的根的分布。我们讨论了最近的结果在这个方向上,这表明,相关的点在球(通过球极平面投影)是令人惊讶的非常适合相对于最小对数能量的领域。

英文摘要:

This article is divided in two parts. In the first part we review some recent results concerning the expected number of real roots of random system of polynomial equations. In the second part we deal with a different problem, namely, the distribution of the roots of certain complex random polynomials. We discuss a recent result in this direction, which shows that the associated points in the sphere (via the stereographic projection) are surprisingly well-suited with respect to the minimal logarithmic energy on the sphere.
