ISM Symposium
Packing and Random Packing

The Institute of Statistical Mathematics
4-6-7 Minami-Azabu, Minato-ku, Tokyo

March 1-3, 2006

Last Update: Feburuary 27, 2006

The scope of our symposium

Discrete geometry is successfully applied to problems in Crystallography and Chemistry. Analyses on statistical data on geometrical structure suggest various problems in statistics. The aim of this symposium is to make an interdisciplinary interaction on Chemistry, Crystallography, Discrete Geometry and Statistics for the new developments of these fields considering the problems on packing and random packing.
