This file provides basic notions of virtual character theory:
'Z[S, A] == collective predicate for the phi that are Z-linear
combinations of elements of S : seq 'CF(G) and have
support in A : {set gT}.
'Z[S] == collective predicate for the Z-linear combinations of
elements of S.
'Z[irr G] == the collective predicate for virtual characters.
dirr G == the collective predicate for normal virtual characters,
i.e., virtual characters of norm 1:
mu \in dirr G <=> m \in 'Z[irr G] and ' [mu] = 1
<=> mu or - mu \in irr G.
> othonormal subsets of 'Z[irr G] are contained in dirr G.
dIirr G == an index type for normal virtual characters.
dchi i == the normal virtual character of index i.
of_irr i == the (unique) irreducible constituent of dchi i:
dchi i = 'chi(of_irr i) or - 'chi(of_irr i).
ndirr i == the index of - dchi i.
dirr1 G == the normal virtual character index of 1 : 'CF(G), the
principal character.
dirr_dIirr j f == the index i (or dirr1 G if it does not exist) such that
dchi i = f j.
dirr_constt phi == the normal virtual character constituents of phi:
i \in dirr_constt phi <=> [dchi i, phi] > 0.
to_dirr phi i == the normal virtual character constituent of phi with an
irreducible constituent i, when i \in irr_constt phi.
