摘要

我们证明了在环空的扩展过程中，集中在同心圆上某些点上的离散有符号测量的相对于环空的绿色能量与对称点上的有符号测量的能量之差不减小。作为推论，得到了classicalPólya-Schur不等式对复数的推广。一些开放问题被公式化。

Green energy of discrete signed measure on concentric circles

We show that the difference between the Green energy of a discrete signed measure relative to a circular annulus concentrated at some points on concentric circles and the energy of the signed measure at symmetric points is non-decreasing during the expansion of the annulus. As a corollary, generalizations of the classical Pólya-Schur inequality for complex numbers are obtained. Some open problems are formulated.
