A day about the Delsarte bound

Monday October 29, 2007 (9:00 - 18:00).

A scientific fest in honor of Philippe Delsarte, emeritus

A question : let us imagine a lot of balls with the same radius. What is the best configuration of such balls when you want to pack it at best ? The discussion began with Newton, Gregory, Kepler, and many other ones. The question seems naive but it is strongly related to information theory (Shannon), combinatorics, quantum communication, error-correcting codes, energy, puzzles, ... It is the so-called kissing problem (for balls).

Philippe Delsarte gave us close bounds on the number of balls using linear programming...

Our invitation to an exclusive day with many living experts in the world.
