Sur l'application des périodes d'une Variation de Structure de Hodge attachée aux familles d'hypersurfaces á singularités simples

Let $n$ be a positive even integer and $d$ a positive integer . To every complete family $Z$ of n dimensional degree d hypersurfaces in the projective space with isolated A-D-E singularities we construct according to an idea of Carlson-Toledo a Deligne-Mumford stack $\bar Z$ whose moduli space is $Z$ such that the monodromy representation extends. We study the corresponding periods mapping and establish an infinitesimal Torelli theorem along the isosingular strata of lZ$under transversality assumptions. We apply this result to prove Steiness of the universal covering space of$\bar Z$.
