• [ Groupe de travail Géométrie discrète du GdR IM ] : 21 novembre 2008 in Chambéry.
  We organize the next Workshop on Discrete Geometry in Chambéry, which gathers the whole french community on this subject.
• [ Groupe de travail Rhône-Alpin en géométrie discrète ]. The LAMA laboratory of Chambéry, the LIRIS laboratory of Lyon, and the GIPSA-lab of Grenoble, have a common workgroup on discrete geometry, with regular seminars. The location turns between the three sites.
