This project is conducted by the CREM under a research contract  with the Communauté Française de Belgique. Our unit contributes
to it with the  help of academic personal (Buekenhout, Parker, Sengier), of researchers  on partial contracts (Bouckaert, Gossez,
M. Frédérickx) and free  researchers (M. Lartillier, C. Frédérickx) looking for situations  giving sense to numbers, to
geometry and to functions.
