Cette note décrit une méthode élémentaire pour calculer lʼindice topologique dʼun champ de vecteurs en une singularité isolée dʼintersection complète quasi-homogène. La méthode est basée sur une variante du lemme de De Rham pour les intersections complètes, qui est utilisée pour calculer lʼindice homologique des champs de vecteurs introduit par X. Gómez-Mont.
In this note an elementary method for computing the topological index of a vector field at a quasihomogeneous isolated complete intersection singularity is described. It is based on a variant of the De Rham lemma for complete intersections, which is used for calculation of the homological index of vectors fields introduced by X. Gómez-Mont.
