Outline

Part I Introduction to the Fekete problem and
to the Forces Method
4
The Fekete problem
The search of the regularity
Stone models of the five Platonic polyhedra. They
date from about 2000BC and are kept in the
Ashmolean Museum in Oxford (figure extracted from
a work by Atiyah and Sutcliffe).
5
The Fekete problem
Best-packing problem Maximize the minimum
distance between points constraints.
(Nurmela)
The solutions of this problem define lattices
that exhibite a high degree of regularity
(many equilateral triangles).
