Exceptional poles of local spinor L‐functions of GSp(4) with anisotropic Bessel models

Abstract

AbstractFor noncuspidal irreducible admissible representations of GSp(4, k) over a local non‐Archimedean field k, we determine the exceptional poles of the spinor L‐factor attached to anisotropic Bessel models by Piatetski–Shapiro. This completes the classification of spinor L‐factors for GSp(4, k).
