大q拉盖尔多项式

大q-拉盖尔多项式是一个以基本超几何函数定义的正交多项式:

${\displaystyle P_{n}(x;a,b;q)={\frac {1}{(b^{-1}*q^{-n};q,n)}}*_{2}\Phi _{1}(q^{-n},aqx^{-1};aq|q;{\frac {x}{b}})}$

极限关系

大q雅可比多项式→大q拉盖尔多项式

令大q雅可比多项式中的${\displaystyle b=0}$,即得大q拉盖尔多项式

${\displaystyle P_{n}(x;a,0,c;q)=P_{n}(x;a,c;q)}$

大q拉盖尔多项式→小q拉盖尔多项式

在大q拉盖尔多项式中，令${\displaystyle x\to bqx}$,并令${\displaystyle b\to \infty }$即得小q拉盖尔多项式 ${\displaystyle \lim _{b\to \infty }P_{n}(bqx;a,b;q)=p_{n}(x;a|q)}$

大→q拉盖尔多项式→阿尔-萨拉姆-卡里兹多项式 I
