Distinguished representations for $SL (n, F)$

Kwangho Choiy, Shiv Prakash Patel

Let $F$ be a finite field, and let $E$ be either a quadratic field extension $E / F$ or the split algebra $F \oplus F$ . We study distinguished representations of $\rm{SL}_{2…

Component groups for non-supercuspidal $L$ -parameters for $p$ -adic $SL_{3}$

Kwangho Choiy, Doyon Kim, Razan Taha +1

We explicitly classify all the component groups associated to the non-supercuspidal, tempered $L$ -parameters of $SL_{3} (F)$ for a $p$ -adic field $F$ of characteristic $0$ by…

Distinguished Representations for $SL_{n} (D)$ where $D$ is a quaternion division algebra over a $p$ -adic field

Kwangho Choiy, Shiv Prakash Patel

Let $D$ be a quaternion division algebra over a non-archimedean local field $F$ of characteristic zero. Let $E / F$ be a quadratic extension and $\rm{SL}_{n}^{*}(E) = {\rm{GL}}_{n}(E…

Representations of the $p$ -Adic $GS p i n_{4}$ and $GS p i n_{6}$ and the Adjoint L-Function

Mahdi Asgari, Kwangho Choiy

We prove a conjecture of B. Gross and D. Prasad about determination of generic $L$ -packets in terms of the analytic properties of the adjoint $L$ -function for $p$ -adic general even…

On compatibility in restriction of Arthur's conjecture for $R$ -groups

Kwangho Choiy

We study the compatibility of Arthur's conjecture for $R$ -groups in the restriction of discrete series representations from Levi subgroups of a $p$ -adic group to those of its close…

Weakly unramified representations, finite morphisms, and Knapp-Stein $R$ -groups

Kwangho Choiy

We transfer Knapp-Stein $R$ -groups for unitary weakly unramified characters between a $p$ -adic quasi-split group and its non-quasi-split inner forms, and provide the structure of t…

Generalized pseudo-coefficients of discrete series of $p$ -adic groups

Kwangho Choiy

Let $G$ be a connected reductive group over a $p$ -adic field $F$ of characteristic 0 and let $M$ be an $F$ -Levi subgroup of $G .$ Given a discrete series representation $σ$ of $M(F)…

Behavior of $R$ -groups for $p$ -adic inner forms of quasi-split special unitary groups

Kwangho Choiy, David Goldberg

We study $R$ -groups for $p$ -adic inner forms of quasi-split special unitary groups. We prove Arthur's conjecture, the isomorphism between the Knapp-Stein $R$ -group and the Langland…

The local Langlands conjecture for the $p$ -adic inner form of Sp(4)

Kwangho Choiy

This paper proves the local Langlands conjecture for the non quasi-split inner form Sp(1,1) of Sp(4) over a p-adic field of characteristic 0, by studying the restriction of represe…

Local Langlands Conjecture for $p$ -adic $GS p i n_{4},$ $GS p i n_{6},$ and their inner forms

Mahdi Asgari, Kwangho Choiy

We establish the local Langlands conjecture for small rank general spin groups $GS p i n_{4}$ and $GS p i n_{6}$ as well as their inner forms. We construct appropriate $L$ -packets and prove…

Invariance of R-groups between p-adic inner forms of quasi-split classical groups

Kwangho Choiy, David Goldberg

We study the reducibility of parabolically induced representations of non-split inner forms of quasi-split classical groups. The isomorphism of Arthur R-groups, endoscopic R-groups…

Transfer of Plancherel Measures for Unitary Supercuspidal Representations between p-adic Inner Forms

Kwangho Choiy

Let $F$ be a $p$ -adic field of characteristic 0, and let $M$ be an $F$ -Levi subgroup of a connected reductive $F$ -split group such that $Π_{i=1}^{r} SL_{n_i} \subseteq M \subseteq…

On multiplicity in restriction of tempered representations of $p$ -adic groups

Kwangho Choiy

We establish an equality between two multiplicities: one in the restriction of tempered representations of a $p$ -adic group to its closed subgroup with the same derived group; and…

Transfer of R-groups between p-adic inner forms of SL_n

Kwangho Choiy, David Goldberg

We study the Knapp-Stein $R$ --groups for inner forms of the split group $S L_{n} (F),$ with $F$ a $p$ --adic field of characteristic zero. Thus, we consider the groups $S L_{m} (D),$ with $…
