Abstract: The wavefront set is a powerful harmonic analytic invariant attached to representations of p-adic groups that is expected to play an important role in the construction of Arthur packets. In this talk I will present new results relating it to the local Langlands correspondence for representations in the principal block. In the process I will introduce a natural refinement of the (geometric) wavefront set with many nicer properties and use it to construct some unipotent Arthur packets of arbitrary split groups. The results are based on joint work with Dan Ciubotaru and Lucas Mason-Brown.
