Weight- Newton-stratum classicality conjecture
Weight- Newton-stratum classicality conjecture
Let be the group in the source, let be the specified minuscule cocharacter, let be the geometric locally analytic de Rham complex of weight , and let be the natural immersion for . Weight- classicality conjecture. For every , the group
has a generalized Hecke eigenspace decomposition by classical eigensystems of weight . Consequently,
has such a decomposition as well. This is a proposed classicality statement for the Newton-stratum pieces and their global geometric de Rham cohomology; no resolution is given in the supplied text.
