～　Stochastic Models and Discrete Geometry　～

The scope of symposium

Discrete geometry is so far successfully applied to problems in Crystallography, Chemistry, Physics, Biology and other fields. Analyses of statistical data on geometrical structure suggest various interesting problems in statistics. The aim of this symposium is to make an interdesciplinary interaction of Crystallography, Chemistry, Physics, Biology, Discrete Geometry and Statistics for the new development of these fields concentrating on the problems of Stochastic Models.
