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…
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 $…
Traverso's Isogeny Conjecture for Some Unitary p-Divisible Groups
Emerald Andrews, Deewang Bhamidipati, Maria Fox +3
The isogeny cutoff of a -divisible group (defined over an algebraically closed field of characteristic ) measures the amount of -torsion necessary to determine its iso…
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…
Frobenius distributions of low dimensional abelian varieties over finite fields
Santiago Arango-Piñeros, Deewang Bhamidipati, Soumya Sankar
Given a -dimensional abelian variety over a finite field , the Weil conjectures imply that the normalized Frobenius eigenvalues generate a multiplicative group…
