Abstract

Nous construisons un modèle local pour les schémas de Hilbert–Siegel de niveau Γ1(p), lorsque p est non-ramifié dans le corps totalement réel. Notre outil clé est une variante du complexe de Lie anneau-équivariant défini par Illusie.

We construct a local model for Hilbert–Siegel moduli schemes with Γ1(p)-level structures, when p is unramified in the totally real field. Our key tool is a variant of the ring-equivariant Lie complex defined by Illusie.
