We consider the group $SL_2(K)$, where $K$ is a local non-archimedean field of characteristic two. We prove that the depth of any irreducible representation of $SL_2 (K)$ is larger than the depth of the corresponding Langlands parameter, with equality if and only if the L-parameter is essentially tame. We also work out a classification of all $L$-packets for $SL_2 (K)$ and for its non-split inner form, and we provide explicit formulae for the depths of their $L$-parameters.
If $E/F$ is a quadratic extension $p$-adic fields, we first prove that the $mathrm{SL}_n(F)$-distinguished representations inside a distinguished unitary L-packet of $mathrm{SL}_n(E)$ are precisely those admitting a degenerate Whittaker model with re
This paper begins the project of defining Arthur packets of all unipotent representations for the $p$-adic exceptional group $G_2$. Here we treat the most interesting case by defining and computing Arthur packets with component group $S_3$. We also s
Let $SL_2$ be the rank one simple algebraic group defined over an algebraically closed field $k$ of characteristic $p>0$. The paper presents a new method for computing the dimension of the cohomology spaces $text{H}^n(SL_2,V(m))$ for Weyl $SL_2$-modu
We investigate various ways to define an analogue of BGG category $mathcal{O}$ for the non-semi-simple Takiff extension of the Lie algebra $mathfrak{sl}_2$. We describe Gabriel quivers for blocks of these analogues of category $mathcal{O}$ and prove
Let $K$ be a non-archimedean local field. In the local Langlands correspondence for tori over $K$, we prove an asymptotic result for the depths.
