Soit un germe de courbe plane défini par une équation réduite f. On démontre qu'un idéal fractionnaire I de D vérifie une propriété de symétrie avec son dual, et on applique ce résultat à l'étude du comportement du module des résidus logarithmiques de D dans le cas de déformations équisingulières.
Let be a plane curve germ defined by a reduced equation f. We prove that a fractional ideal I of D satisfies a symmetry property with its dual, and then apply it to study the behavior of the module of logarithmic residues of D in equisingular deformations.
