Splitting fields of real irreducible representations of finite groups

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...
