Ekedahl-Oort strata with a superspecial factor in unitary Shimura varieties

Emerald Andrews, Deewang Bhamidipati, Heidi Goodson +2

Let be an algebraically closed field of characteristic and let be an imaginary quadratic order in which is inert. For any …

On the classification of indecomposable Ekedahl-Oort strata in unitary Shimura varieties, and related Newton polygons

Emerald Andrews, Deewang Bhamidipati, Maria Fox +3

In this paper, we give a complete classification of indecomposable Ekedahl--Oort strata of Shimura varieties associated to the unitary group over an odd inert p…

Ekedahl-Oort types of -covers in characteristic

Jeremy Booher, Steven R. Groen, Joe Kramer-Miller

In this article we study the Ekedahl-Oort types of -Galois covers in characteristic two. When the base curve is ordinary, we show that the E…

The Ekedahl-Oort and Newton stratification of the Shimura variety

Emerald Andrews, Deewang Bhamidipati, Maria Fox +3

This paper concerns the characteristic- fibers of Shimura varieties. Such Shimura varieties parametrize abelian varieties in characteristic of dimension $…

Analogues of Traverso's Isogeny Conjecture for Some Unitary p-Divisible Groups

Emerald Andrews, Deewang Bhamidipati, Maria Fox +3

Let be a prime and an algebraically closed field of characteristic . Two invariants worthy of study for a -divisible group over are its isogeny cutoff…

Ekedahl-Oort strata in the Shimura variety

Emerald Andrews, Deewang Bhamidipati, Maria Fox +3

This paper concerns the characteristic- fibers of Shimura varieties, which classify abelian varieties with additional structure. These Shimura varieties adm…
