Invariants de Hasse $\mu$-ordinaires

In this article, we construct in a purely local way partial (Hasse) invariants for $p$-divisible groups with given endomorphisms, using crystalline cohomology. Theses invariants generalises the classical Hasse invariant, and allow us to study families of such groups. We also study a few geometric properties of theses invariants. Used in the context of Shimura varieties, for example, theses invariants are detecting some Newton strata, including the $\mu$-ordinary locus.
