Q拉卡多項式

Q拉卡多項式是以基本超幾何函數定義的多項式：

p_{n}(q^{-x}+q^{x+1}cd;a,b,c,d;q)={}_{4}\phi _{3}\left[{\begin{matrix}q^{-n}&abq^{n+1}&q^{-x}&q^{x+1}cd\\aq&bdq&cq\\\end{matrix}};q;q\right]

極限關係

在Q拉卡多項式中令 $\beta =0$ 以及 $\alpha {q}=q^{-N}$ ,即得雙q哈恩多項式：

$R_{n}(\mu (x);q^{-N-1},0,\gamma ,\delta |q)=R_{n}(\mu (x);\gamma ,\delta ,N|q)$

令Q拉卡多項式中 $a=b$ , $cq=q^{-N}$ 即得雙Q克拉夫楚克多項式
