Abstract
Let π be an irreducible admissible unitary ψ-generic representation of the non-archimedean general linear group GL2n(F), which admits an (η, psi;)-Shalika model Sψη(π). In this paper, we show the nonvanishing of all non-zero Shalika newvectors So ∈ Sψη(π) at the identity matrix g = id ∈ GL2n(F), if η is unramified. This complements the analogous result for Whittaker newvectors, which can be read off the formulae established independently by Miyauchi in [Miy14] and the second named author in [Mat13].
