连续q拉盖尔多项式

连续q拉盖尔多项式(Continuous q-Laguerre polynomials)是一个以基本超几何函数定义的正交多项式^[1]。

3rd order Continuous q Laguerre polynomials

${\displaystyle P_{n}^{(\alpha )}(x|q)={\frac {(q^{\alpha }+1;q)_{n}}{(q;q)_{n}}}}$${\displaystyle _{3}\Phi _{2}(q^{-n},q^{\alpha /2+1/4}e^{i\theta },q^{\alpha /2+1/4}*e^{-i\theta };q^{\alpha +1},0|q,q)}$

极限关系

Q梅西纳-帕拉泽克多项式→连续q拉盖尔多项式

${\displaystyle P_{n}(cos(\theta +\phi );q^{\alpha /2+1/2}|q)=}$${\displaystyle q^{(-\alpha /2-1/4)*n}*P_{n}^{(}\alpha )(cos\theta |q)}$

阿拉-萨拉姆-迟哈剌多项式→连续q拉盖尔多项式

令连续q拉盖尔多项式中${\displaystyle x=q^{x}}$,q→1,即得拉盖尔多项式

验证

3阶连续q拉盖尔多项式： ${\displaystyle \lim _{q\to 1}P_{3}^{(}a)=1/6\,{a}^{3}-x{a}^{2}+{a}^{2}+{\frac {11}{6}}\,a+2\,a{x}^{2}-5\,ax+1-6\,x-4/3\,{x}^{3}+6\,{x}^{2}}$

3阶广义拉盖尔多项式：

${\displaystyle L_{3}^{a}(2x)={\frac {1}{6}}(a+1)_{3}*_{1}F_{1}(-n,a+1;2x)}$ ${\displaystyle =1/6\,{a}^{3}-x{a}^{2}+{a}^{2}+{\frac {11}{6}}\,a+2\,a{x}^{2}-5\,ax+1-6\,x-4/3\,{x}^{3}+6\,{x}^{2}}$

两者显然相等。
