The Field of Values of the Height Zero Characters (2304.12869v1)
Published 25 Apr 2023 in math.GR and math.RT
Abstract: We determine what are the fields of values of the irreducible $p$-height zero characters of all finite groups for $p=2$; we conjecture what they should be for odd primes, and reduce this statement to a problem on blocks of quasi-simple groups.
