Title: Normalization of closed Ekedahl-Oort strata,
Abstract: We apply our theory of partial flag spaces developed in previous articles to
study a group-theoretical generalization of the canonical filtration of a
truncated Barsotti-Tate group of level 1. As an application, we determine
explicitly the normalization of the Zariski closures of Ekedahl-Oort strata of
Shimura varieties of Hodge-type as certain closed coarse strata in the
associated partial flag spaces.
