Character codegrees of maximal class p-groups

Group Theory 2018-09-21 v1

Abstract

Let GG be a pp-group and let χ\chi be an irreducible character of GG. The codegree of χ\chi is given by G:ker(χ)/χ(1)|G:\text{ker}(\chi)|/\chi(1). If GG is a maximal class pp-group that is normally monomial or has at most three character degrees then the codegrees of GG are consecutive powers of pp. If G=pn|G|=p^n and GG has consecutive pp-power codegrees up to pn1p^{n-1} then the nilpotence class of GG is at most 2 or GG has maximal class.
