Query: Twisted endoscopy from a sheaf-theoretic perspective   The standard theory of endoscopy for real groups has two parallel
formulations. The original formulation of Langlands and Shelstad relies on
methods in harmonic analysis. The subsequent formulation of Adams, Barbasch and
Vogan relies on sheaf-theoretic methods. The original formulation was extended
by Kottwitz and Shelstad to twisted endoscopy. We extend the sheaf-theoretic
formulation to the context of twisted endoscopy and provide applications for
computing Arthur packets.
