Special unipotent representations of simple linear Lie groups of type A

Representation Theory 2023-11-01 v2

Abstract

Let G be a special linear group over the real, the complex or the quaternion, or a special unitary group. In this note, we determine all special unipotent representations of G in the sense of Arthur and Barbasch-Vogan, and show in particular that all of them are unitarizable.
