Abstract
We construct a local model for Hilbert-Siegel moduli schemes with -level bad reduction over , where is a prime unramified in the totally real field and is the residue cardinality over . Our main tool is a variant over the small Zariski site of the ring-equivariant Lie complex defined by Illusie in his thesis, where is a commutative ring and is a scheme of -modules. We use it to calculate the -equivariant Lie complex of a Raynaud group scheme, then relate the integral model and the local model.
