IRREDUCIBILITY OF NEWTON STRATA IN GU(1, n− 1) SHIMURA VARIETIES
نویسنده
چکیده
Let L be a quadratic imaginary field, inert at the rational prime p. Fix an integer n ≥ 3, and let M be the moduli space (in characteristic p) of principally polarized abelian varieties of dimension n equipped with an action by OL of signature (1, n−1). We show that each Newton stratum of M, other than the supersingular stratum, is irreducible.

Truncations of Level 1 of Elements in the Loop Group of a Reductive Group
We generalize the notion of Ekedahl-Oort strata to elements in the loop group of any connected reductive group, and call the resulting discrete invariant the truncation of level 1 of the element. We give conditions for the Newton points occurring among the elements of a given truncation of level 1 and especially for the generic Newton point in a given truncation stratum. We prove that truncatio...
متن کاملDimensions of Newton Strata in the Adjoint Quotient of Reductive Groups
In [Cha00] Chai made a conjecture on the codimensions of Newton strata in Shimura varieties, which then led Rapoport [Rap05] to his conjecture on dimensions of affine Deligne-Lusztig varieties inside affine Grassmannians. The main goal of this paper is to show that exactly the same codimensions arise in a simpler context, that of the Newton stratification in the adjoint quotient of a reductive ...

متن کاملA geometric Jacquet-Langlands correspondence for U(2) Shimura varieties
Let G be a unitary group over Q, associated to a CM-field F with totally real part F, with signature (1, 1) at all the archimedean places of F. For certain primes p, and X a Shimura variety associated to G with good reduction at p, we construct a stratification of the characteristic p fiber of X , whose closed strata are indexed by subsets S of the archimedean places of F. Certain closed strata...
متن کاملParametrizing Shimura Subvarieties of A1 Shimura Varieties and Related Geometric Problems
This paper gives a complete parametrization of the commensurability classes of totally geodesic subspaces of irreducible arithmetic quotients of Xa,b = (H ) × (H). A special case describes all Shimura subvarieties of type A1 Shimura varieties. We produce, for any n ≥ 1, examples of manifolds/Shimura varieties with precisely n commensurability classes of totally geodesic submanifolds/Shimura sub...
