Parametrization and reduction to depth zero of $Z [\frac{1}{p}]$ -blocks of tame $p$ -adic groups

Jean-FranÃ§ois Dat, Jessica Fintzen

Let $G$ be a reductive group over a non-archimedean local field $F$ of residue characteristic $p$ . We consider pairs $(I ¨ , I)$ consisting of a "wild inertia" Langlands parameter $Ï…

Depth zero representations over $Z [\frac{1}{p}]$

Jean-FranÃ§ois Dat, Jean-François Dat, Thomas Lanard

We consider the category of depth $0$ representations of a $p$ -adic quasi-split reductive group with coefficients in $Z [\frac{1}{p}]$ . We prove that the blocks…

Local Langlands in families: The banal case

Jean-FranÃ§ois Dat, David Helm, Robert Kurinczuk +1

We state a conjecture, local Langlands in families, connecting the centre of the category of smooth representations on $Z [q^{- 1}]$ -modules of a quasi-split $p$ -adic…
