Dirac series of $E_{8(-24)}$

Representation Theory 2025-03-18 v1

Abstract

This paper classifies the Dirac series of E8(24)E_{8(-24)}, the linear quaternionic real form of complex E8E_8. One tool for us is a further sharpening of the Helgason-Johnson bound in 1969. Our calculation continues to support Vogan's fundamental parallelepiped conjecture.
