Soit γ une solution algébrique de degré δ d'un d-tissu non-dicritique sur le plan projectif. On donne une formule qui relie d et δ à des indices dont le support est la réunion du lieu singuler de γ et de l'intersection de la courbe avec le discriminant du tissu.
Let γ be an algebraic solution of a non-dicritical d-web in the complex projective plane. We give a formula relating global data (degree of the solution and of the web) to local data (some indices supported on the union of the singular set of γ with the intersection of the curve with the discriminant of the web).
