Abstract

The object of our investigation is a point that gives the maximum value of a potential with a strictly decreasing radially symmetric kernel. It defines a center of a body in $\mathbb {R}^m$. When the kernel is the Riesz kernel or the Poisson kernel, such a center is called an $r^{\alpha -m}$-center or an illuminating center, respectively.

The existence of a center is easily shown but uniqueness does not always hold. The main results in this paper are some new sufficient conditions for the uniqueness.
