L-packets over strong real forms

Representation Theory 2022-08-08 v1

Abstract

Langlands defined L-packets for real reductive groups. In order to refine the local Langlands correspondence, Adams-Barbasch-Vogan combined L-packets over all real forms belonging to an inner class. Using different methods, Kaletha also defines such combined L-packets with a refinement to the local Langlands correspondence. We prove that the L-packets of Adams-Barbasch-Vogan and Kaletha are the same and are parameterized identically.
