Q貝塞爾多項式

qBessel function 2D plot

q-貝塞爾多項式，也稱q-貝塞爾函數，其通過基本超幾何函數定義：

$y_{n}(x;a;q)=\;_{2}\phi _{1}\left({\begin{matrix}q^{-N}&-aq^{n}\\0\end{matrix}};q,qx\right)$

正交關係

$\sum _{k=0}^{\infty }({\frac {a^{k}}{(q;q)_{n}}}*q^{k+1 \choose 2}*y_{m}*(q^{k};a;q)*y_{n}*(q^{k};a;q)=(q;q)_{n}*(-aq^{n};q)_{\infty }{\frac {a^{n}*q^{n+1 \choose 2}}{1+aq^{2n}}}\delta _{mn}$
