"대칭군의 지표(character)에 대한 프로베니우스 공식"의 두 판 사이의 차이

2016년 6월 1일 (수) 20:02 판

개요

슈르 다항식(Schur polynomial)을 이용하여, 대칭군 (symmetric group)의 지표를 계산하는 방법
대칭군 $S_m$의 기약표현은 크기가 m인 영 다이어그램(또는 m의 분할)과 일대일대응된다
m의 분할 $\lambda$에 대응되는 $S_m$의 기약표현의 지표를 $\chi_{\lambda}$ 로 나타내자
$C_{\mathbf{i}}=(1^{i_1},2^{i_2},\cdots,m^{i_m})$를 $i_1+2i_2+\cdots mi_m=m$를 만족시키는 대칭군 $S_m$의 공액류라 하면, $\chi_{\lambda}(C_{\mathbf{i}})$의 값은 다음 프로베니우스 공식으로 주어진다

\[\left(\sum_{l=1}^{m} x_l\right)^{i_1}\left(\sum_{l=1}^{m} x_l^2\right)^{i_2}\cdots \left(\sum_{l=1}^{m} x_l^m\right)^{i_m}=\sum_{\lambda}\chi_{\lambda}(C_{\mathbf{i}})S_{\lambda}(x_1,\cdots, x_m)\] 여기서 $S_{\lambda}$ 는 슈르 다항식(Schur polynomial)

다음과 같이 표현하기도 한다

\[\prod_{j=1}^{m}P_{j}(x)^{i_j}=\sum_{\lambda}\chi_{\lambda}(C_{\mathbf{i}})S_{\lambda}(x_1,\cdots, x_m)\]

예

$S_3$

대칭군 $S_3$ 의 지표 테이블

\begin{array}{c|ccc} & \{1^3\} & \{1^1,2^1\} & \{3^1\} \\ \hline \{3\} & 1 & 1 & 1 \\ \{2,1\} & 2 & 0 & -1 \\ \{1,1,1\} & 1 & -1 & 1 \end{array}

슈르 다항식

\[ \begin{align} S_{(3)} & = &x_1 x_2 x_3+\left(x_1+x_2+x_3\right){}^3-2 \left(x_1+x_2+x_3\right) \left(x_1 x_2+x_1 x_3+x_2 x_3\right) \\ S_{(2,1)} & =&\left(x_1+x_2\right) \left(x_1+x_3\right) \left(x_2+x_3\right) \\ S_{(1,1,1)} &= &x_1 x_2 x_3 \end{align} \]

슈르 다항식과 거듭제곱의 합 (power sum) 대칭다항식

\[ \begin{align} \left(x_1+x_2+x_3\right){}^3&=S_{(3)}+2\cdot S_{(2,1)}+S_{(1,1,1)}\\ \left(x_1+x_2+x_3\right) \left(x_1^2+x_2^2+x_3^2\right)& = S_{(3)}+0\cdot S_{(2,1)}-S_{(1,1,1)}\\ x_1^3+x_2^3+x_3^3&=S_{(3)}-1\cdot S_{(2,1)}+S_{(1,1,1)} \end{align} \]
