Griffiths-Schmid conditions for automorphic forms via characteristic $p$

Wushi Goldring, Jean-Stefan Koskivirta

We establish vanishing results for spaces of automorphic forms in characteristic $0$ and characteristic $p$ . We prove that for Hodge-type Shimura varieties, the weight of any nonze…

Divisibility of mod $p$ automorphic forms and the cone conjecture for certain Shimura varieties of Hodge-type

Wushi Goldring, Jean-Stefan Koskivirta

For several Hodge-type Shimura varieties of good reduction in characteristic $p$ , we show that the cone of weights of automorphic forms is encoded by the stack of $G$ -zips of Pink-…

Weights of mod $p$ automorphic forms and partial Hasse invariants

Wushi Goldring, Naoki Imai, Jean-Stefan Koskivirta

For a connected, reductive group $G$ over a finite field endowed with a cocharacter $μ$ , we define the zip cone of $(G, μ)$ as the cone of all possible weights of mod $p$ automorphi…
