Splitting fields of real irreducible representations of finite groups
<p>We show that any irreducible representation ρ of a finite group G of exponent n, realisable over R, is realisable over the field E:= Q(ζn) ∩ R of real cyclotomic numbers of order n, and describe an algorithmic procedure transforming a reali...
