On smooth-group actions on reductive groups and spherical buildings

Jeffrey D. Adler, Joshua M. Lansky, Loren Spice

Let $k$ be a field, and suppose that $Γ$ is a smooth $k$ -group that acts on a connected, reductive $k$ -group $G$ . Let $G$ denote the maximal smooth, connected subgroup o…

Root data with group actions

Jeffrey D. Adler, Joshua M. Lansky

Suppose $k$ is a field, $G$ is a connected reductive algebraic $k$ -group, $T$ is a maximal $k$ -torus in $G$ , and $Γ$ is a finite group that acts on $(G, T)$ . From the above, one obt…

A Real Groups Construction of the Tame Local Langlands Correspondence for PGSp(4,F)

Moshe Adrian, Joshua Lansky

In this paper, we continue the work of the first author and give a new construction of the tame local Langlands correspondence for PGSp(4,F), where F is a p-adic field, that is ana…

Lifting representations of finite reductive groups: a character relation

Jeffrey D. Adler, Michael Cassel, Joshua M. Lansky +2

Given a connected reductive group $G ~$ over a finite field $k$ , and a semisimple $k$ -automorphism $ε$ of $G ~$ of finite order, let $G$ denote the connected…

Lifting representations of finite reductive groups II: Explicit conorms

Jeffrey D. Adler, Joshua M. Lansky

Let $k$ be a field, $G ~$ a connected reductive $k$ -group, and $Γ$ a finite group. In a previous work, the authors defined what it means for a connected reductive $k$ -group $…

Distinguished Tame Supercuspidal Representations and Odd Orthogonal Periods

Jeffrey Hakim, Joshua Lansky

We further develop and simplify the general theory of distinguished tame supercuspidal representations of reductive $p$ -adic groups due to Hakim and Murnaghan, as well as the analo…
