The regular Kim–Yu type realization conjecture
The regular Kim–Yu type realization conjecture
Assume that is not bad for , and let be an unramified Howe-factorizable pair. Let be a Howe factorization for , and let denote the modified positive-depth Deligne–Lusztig representation defined from this factorization. Let be the associated parahoric quotient and the subgroup carrying the associated Kim–Yu type. Regular Kim–Yu type realization conjecture. The representation of is a linear combination of Bushnell–Kutzko types, and its restriction to contains the AFMO-twisted Kim–Yu type associated to . This would provide a general realization of regular Kim–Yu types through modified positive-depth Deligne–Lusztig induction; the statement is presented as a conjecture, with no resolution given here.
