코스트카 수

$$s_\lambda(\mathbb{x})= \sum_\mu K_{\lambda\mu}m_\mu(\mathbb{x})$$


코스트카 다항식

$$ s_\lambda(\mathbb{x})= \sum_\mu K_{\lambda\mu}(q)P_\mu(\mathbb{x},q) $$


라스꾸-슈첸베르제 (Lascoux-Schützenberger) 공식

  • 1978년에 라스꾸와 슈첸베르제는 $K_{\lambda,\mu}(q)$가 음이 아닌 정수 계수 다항식임을 증명
  • They proved this by showing that $K_{\lambda,\mu}(q)=\sum q^{c(T)}$, where $T$ varies over all semi-standard tableaux of shape $\lambda$ and weight $\mu$ and $c(T)$ is an integer-valued function, called the charge of the tableau $T$, which is still a mysterious object in combinatorics.
