On Arthur packets containing a fixed tempered representation

Representation Theory 2026-02-16 v1 Number Theory

Abstract

We determine the number of local Arthur packets containing a certain fixed tempered representation for classical pp-adic groups. More specifically, given a tempered extended multi-segment supported in the integers, we determine a count for all extended multi-segments which arise from it through applications of the operators arising from the theory of intersections of local Arthur packets.
