Seminar for Unitary Representations and Automorphic Forms

On Monday, May 15, 2023, 16:00 hours, Emile Takahiro Okada (National University of Singapore) will hold lecture as part of Seminar for Unitary Representations and Automorphic Forms titled:

 The wavefront set of unipotent representations with real infinitesimal character

Abstract: For a reductive group defined over a p-adic field, the wavefront set is an invariant of an admissible representations which roughly speaking measures the direction of the singularities of the character near the identity. Studied first by Roger Howe in the 70s, the wavefront set has important connections to Arthur packets, and has been the subject of thorough investigation in the intervening years. Of the many open questions regarding this invariant, one of main lines of inquiry is to determine the relation between the wavefront and the L-parameter of a representation. In this talk we present new results answering this question for unipotent representations with real infinitesimal character. The results are joint with Dan Ciubotaru and Lucas Mason-Brown.

Lecture will be held via Zoom application:
