Special-points conjecture for Shimura varieties
Special-points conjecture for Shimura varieties
Let be a Shimura -datum, let be its integral model, and let be the algebraic closure of the residue field. A point of with coordinates in is a point of the special fibre, and a special point is a point of the Shimura variety in characteristic zero arising from special homomorphisms. Special-points conjecture. Up to isogeny, every point on with coordinates in lifts to a special point on with coordinates in a finite extension of .
The conjecture is forced by Conjecture LR+ because contains only terms corresponding to special homomorphisms. The source states that it is proved for simple abelian varieties of PEL type by Zink, and cites announced broader results; thus the unrestricted formulation remains open in the supplied context.
