Mod- $p$ maximal compact inductions do not have irreducible admissible subrepresentations

Peng Xu

Let $p$ be a prime number. We show in this short note that mod- $p$ maximal compact inductions of a $p$ -adic split reductive group do not have irreducible admissible subrepresentati…

On certain Iwahori--Hecke modules of $G L_{3}$ in characteristic $p$

Peng Xu

In this note, we show that the natural analogue of certain finiteness result of Barthel--Livn $e ˊ$ on $G L_{2}$ fails for $G L_{3}$ . More precisely, within the pro- $p$ -Iwaho…

On the pro- $p$ -Iwahori invariants of supersingular representations of unramified $U (2, 1)$

Peng Xu

Let $G$ be the unramified unitary group $U (2, 1) (E / F)$ over a non-archimedean local field $F$ of odd residue characteristic $p$ . In this paper, for any supersingular representation…
