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:

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

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$b=0$,即得大q拉盖尔多项式

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

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

大→q拉盖尔多项式→阿尔-萨拉姆-卡里兹多项式 I
