    On the elliptic nonabelian Fourier transform for unipotent representations of p-adic groups by Ciubotaru, D, Opdam, E

    Published 2017
    “…In this paper, we consider the relation between two nonabelian Fourier transforms. The first one is defined in terms of the Langlands-Kazhdan-Lusztig parameters for unipotent elliptic representations of a split p-adic group and the second is defined in terms of the pseudocoefficients of these representations and Lusztig's nonabelian Fourier transform for characters of finite groups of Lie type. …”
