abstract
In this article we study point configurations minimizing the discrete energy on a compact Riemannian manifold, where the energy kernel is taken to be the Green's function for the Laplacian. We show that every point in a minimizing configuration lies inside an open set called harmonic ball where no other point can enter, and that the minimum distance between any two distinct points has the optimal asymptotic order. We compute explicit bounds for the minimum distance in the case of Compact Rank One Symmetric Spaces.

For sufficiently large equal charges, the boundary of the equilibrium droplet on the sphere is the stereographic projection of an ellipse, and a mother body is obtained from a weakly admissible equilibrium problem on the real line.

An equilibrium problem on the sphere with two equal charges
For sufficiently large equal charges, the boundary of the equilibrium droplet on the sphere is the stereographic projection of an ellipse, and a mother body is obtained from a weakly admissible equilibrium problem on the real line.
