Universal polar dual pairs of spherical codes found in $E_{8}$ and $Λ_{24}$

S. V. Borodachov, P. G. Boyvalenkov, P. D. Dragnev +3

We identify universal polar dual pairs of spherical codes $C$ and $D$ such that for a large class of potential functions $h$ the minima of the discrete $h$ -potential of $C$ on the…

Riesz equilibrium on a ball in the external field of a point charge

Peter D. Dragnev, Ramon Orive, Eduard B. Saff +1

We investigate the Riesz energy minimization problem on a $d$ -dimensional ball in the presence of an external field created by a point charge above the ball in $R^{d + 1}$ , $d \geq 1$ …
