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.
