Bifurcations imparfaites de type pontentiel et D-équivalences de déformations des fonctions
This paper is an important contribution to the study of bifurcation diagrams introduced by \textit{M. Golubitsky} and \textit{D. Schaeffer} [Commun. Pure Appl. Math. 32, 21-98 (1979; Zbl 0409.58007)]. The classification of the bifurcation diagrams with D-codimension \(\leq 2\) (i.e. those which occur in generic 2-parameters families) is given.
