Generic torsion vanishing conjecture for Shimura varieties
Let be a Shimura datum such that is unramified, and let be a sufficiently small level with hyperspecial. Set . A maximal ideal is generic when its associated toral -parameter satisfies the genericity condition described in the surrounding text. Generic torsion vanishing conjecture. If is generic, then the cohomology of
is concentrated in degrees , while the cohomology of
is concentrated in degrees . This predicts torsion-vanishing ranges for localized cohomology under a genericity hypothesis; the source motivates it by known results for general linear groups, but supplies no resolution.
