大q雅可比多项式

大q-雅可比多项式(英語:Big q-Jacobi polynomials)是一个以基本超几何函数定义的正交多项式[1]

BIG Q JACOBI 2D Maple PLOT
P n ( x ; a , b , c ; q ) = 3 ϕ 2 ( q n , a b q n + 1 , x ; a q , c q ; q , q ) {\displaystyle \displaystyle P_{n}(x;a,b,c;q)={}_{3}\phi _{2}(q^{-n},abq^{n+1},x;aq,cq;q,q)}

正交性

大q-雅可比多项式满足下列正交关系

x ( p n ( x ) p m ( x ) | x | v x = h n δ m n {\displaystyle \sum _{x}(p_{n}(x)*p_{m}(x)|x|v_{x}=h_{n}*\delta _{m}n}

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