数学上,诱导特征标是指由一个有限群 G 的子群 H ≤ G 的表示 W 诱导得到的 G 的表示V 的特征标。一般地,也有H 上的类函数f 的诱导类函数,由下面的公式给出: 若 f 是 H 的表示 W 的一个特征标,用这个公式就可以计算 G 的诱导表示 V 的特征标。 关于诱导特征标的基本结果是,其指出 G 上的每个不可约特征标都是初等子群的特征标诱导而来的指标的整系数线性组合。

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 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.

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 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.
