In mathematics, an induced character is the character of the representation V of a finite group G induced from a representation W of a subgroup H ⤠G. More generally, there is also a notion of induction of a class function f on H given by the formula
If f is a character of the representation W of H, then this formula for calculates the character of the induced representation V of G.
The basic result on induced characters is Brauer's theorem on induced characters. It states that every irreducible character on G is a linear combination with integer coefficients of characters induced from elementary subgroups.
