"Le changement de cadres est un moyen d'obtenir des formulations d'un problème qui sans être nécessairement tout à fait équivalentes, permettent un nouvel accès aux difficultés rencontrées et la mise en œuvre d'outils techniques qui ne s'imposaient pas dans la première formulation." (Douady 1986 p.11)
• English : Changing of settings
"The changing of settings is a means to obtain different formulations of a problem. It can be a source of imbalance. That is the case if the formulations are not exactly equivalent, but partly corresponding and if the habits and the knowing of the researcher in each setting provoke an imbalance between his expectations and his observations or mathematical results." (Douady 1991 p.116)
