Conjecture on derived ordinary parts of a Bruhat-cell compact induction
Conjecture on derived ordinary parts of a Bruhat-cell compact induction
Let be the Weyl group of , let , let be a locally admissible smooth representation of over , let be a minimal double-coset representative, and let . Let be the associated integer and the associated algebraic character of . Derived ordinary-parts conjecture. There is a natural -linear isomorphism
This would compute derived ordinary parts cell by cell in the Bruhat filtration of parabolic induction, a key step toward understanding derived ordinary parts of induced representations. The statement is presented as a conjecture, and no resolution status is supplied in the source.
