Abstract: In his most recent book, Arthur defines A(rthur)-packets for classical groups using techniques from harmonic analysis.

For real groups an alternative approach to the definition of A-packets has been known since the early 90s. This approach, due

to Adams-Barbasch-Vogan, relies on sheaf-theoretic techniques instead of harmonic analysis. We will report on work in progress,

joint with J. Adams and P. Mezo, in proving that these two constructions of A-packets, defined through two fundamentally different

points of view are the same for classical groups.
