Buzzard–Diamond–Jarvis conjecture for quaternionic mod- cohomology
Buzzard–Diamond–Jarvis conjecture for quaternionic mod- cohomology
Let ) be a totally real field and let
be a continuous, irreducible and totally odd representation. Let be a quaternion algebra over that splits at exactly one infinite place, and let be the corresponding localized mod- cohomology representation of . Buzzard–Diamond–Jarvis conjecture. The representation is isomorphic to a restricted tensor product
where each is a smooth admissible representation of , with the following properties: if does not divide , then is the representation attached to by the modulo local Langlands or Jacquet–Langlands correspondence; if divides , then , and, when both and are unramified at , for every irreducible representation of ,
if and only if , where is the associated set of Serre weights. This conjecture predicts a precise local–global description of mod- automorphic forms and relates the local factors at places above to Serre weights; the source does not state a resolution.
