introduction
- 양의 정수 $n$에 대하여, $x=(x_1,\dots,x_n)$로 두자
- Given a partition $\lambda$ such that $l(\lambda)\leq n$, write $x^{\lambda}$ for the monomial $x_1^{\lambda_1}\dots x_n^{\lambda_n}$
- $m_i(\lambda)$ 는 $\lambda=(\lambda_n,\cdots,\lambda_1)$에서 $i$의 개수
- define
\begin{equation} v_{\lambda}(q)=\prod_{i=0}^n \frac{(q)_{m_i}}{(1-q)^{m_i}}, \end{equation}
- The Hall-Littlewood polynomial $P_{\lambda}(x;q)$ is defined as the symmetric function \cite{Macdonald95}
\begin{equation} P_{\lambda}(x;q)=\frac{1}{v_{\lambda}(q)} \sum_{w\in\mathfrak{S}_n} w\bigg(x^{\lambda}\prod_{i<j}\frac{x_i-qx_j}{x_i-x_j}\bigg), \end{equation} where the symmetric group $\mathfrak{S}_n$ acts on $x$ by permuting the $x_i$.
- It follows from the definition that $P_{\lambda}(x;q)$ is a homogeneous polynomial of degree $\lvert\lambda \lvert$,
