Résumé : Which values are possible as the total Milnor number of a degree d projective hypersurface with isolated singularities ? I will first explain how to assign a base point when applying the Lefschetz hyperplane theorem, and use this technique to give an affirmative answer to a conjecture of Dimca and Papadima on the total Milnor number. A more general conjecture on the total Milnor number will be formulated.
