小q雅可比多项式

小q-雅可比多项式(Little q-Jacobi polynomials)是一个以基本超几何函数定义的正交多项式，定义如下^[1].

\displaystyle p_{n}(x;a,b;q)={}_{2}\phi _{1}(q^{-n},abq^{n+1};aq;q,xq)

例子

k=3,

$p=1+q*x/((1-a*q)*(1-q))-q^{2}*x*a*b*q^{n}/((1-a*q)*(1-q))-q*x/((1-a*q)*(1-q)*q^{n})+q^{2}*x*a*b/((1-a*q)*(1-q))$ $(1-q^{(}-n))*(1-q^{(}-n)*q)*(1-a*b*q^{(}n+1))*(1-a*b*q^{(}n+1)*q)*q^{2}*x^{2}/((1-a*q)*(1-a*q^{2})*(1-q)*(1-q^{2}))$ $+(1-q^{(}-n))*(1-q^{(}-n)*q)*(1-q^{(}-n)*q^{2})*(1-a*b*q^{(}n+1))*(1-a*b*q^{(}n+1)*q)*(1-a*b*q^{(}n+1)*q^{2})*q^{3}*x^{3}/((1-a*q)*(1-a*q^{2})*(1-a*q^{3})*(1-q)*(1-q^{2})*(1-q^{3}))$
