On families of degenerate representations of GL_n(F)

Johannes Girsch, David Helm

We consider the stratification of the category of smooth representations of $\mbox{GL}_n(F)$ (for $F$ a $p$ -adic field) induced by degenerate Whittaker models. We show that, remark…

Local Langlands in families: The banal case

Jean-François 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…

Block decompositions for $p$ -adic classical groups and their inner forms

David Helm, Robert Kurinczuk, Daniel Skodlerack +1

For an inner form $G$ of a general linear group or classical group over a non-archimedean local field of odd residue characteristic, we decompose the category of smooth re…
