Microlocal versal deformations of the plane curves yk=xn
Comptes Rendus. Mathématique, Volume 347 (2009) no. 23-24, pp. 1409-1414.

We introduce the notion of microlocal versal deformation of a plane curve. We construct equisingular versal deformations of Legendrian curves that are the conormal of a semi-quasi-homogeneous branch.

On introduit la notion de déformation verselle microlocale d'un germe de courbe plane. Nous construisons la déformation verselle équisingulière du conormal d'un germe de courbe plane irréductible semi-quasi-homogène.
