The LaTeX DLMF and DRMF macro \qinvAlSalamChihara represents the q π‘ž {\displaystyle{\displaystyle q}} -inverse of the Al-Salam Chihara polynomial.

This macro is in the category of polynomials.

In math mode, this macro can be called in the following ways:

\qinvAlSalamChihara{n} produces Q n Al-Salam-Chihara-polynomial-Q 𝑛 {\displaystyle{\displaystyle{\displaystyle Q_{n}}}}
\qinvAlSalamChihara{n}@{x}{a}{b}{q^{-1}} produces Q n ⁑ ( x ; a , b ; q - 1 ) Al-Salam-Chihara-polynomial-Q 𝑛 π‘₯ π‘Ž 𝑏 superscript π‘ž 1 {\displaystyle{\displaystyle{\displaystyle Q_{n}\!\left(x;a,b\,;\,q^{-1}\right% )}}}

These are defined by Q n ⁑ ( \thalf ⁒ ( a ⁒ q - x + a - 1 ⁒ q x ) ; a , b ; q - 1 ) := ( - 1 ) n ⁒ b n ⁒ q - 1 2 ⁒ n ⁒ ( n - 1 ) ⁒ ( ( a ⁒ b ) - 1 ; q ) n ⁒ \qHyperrphis ⁒ 31 ⁒ @ ⁒ @ ⁒ q - n , q - x , a - 2 ⁒ q x ⁒ ( a ⁒ b ) - 1 ⁒ q ⁒ q n ⁒ a ⁒ b - 1 assign Al-Salam-Chihara-polynomial-Q 𝑛 \thalf π‘Ž superscript π‘ž π‘₯ superscript π‘Ž 1 superscript π‘ž π‘₯ π‘Ž 𝑏 superscript π‘ž 1 superscript 1 𝑛 superscript 𝑏 𝑛 superscript π‘ž 1 2 𝑛 𝑛 1 q-Pochhammer-symbol superscript π‘Ž 𝑏 1 π‘ž 𝑛 \qHyperrphis 31 @ @ superscript π‘ž 𝑛 superscript π‘ž π‘₯ superscript π‘Ž 2 superscript π‘ž π‘₯ superscript π‘Ž 𝑏 1 π‘ž superscript π‘ž 𝑛 π‘Ž superscript 𝑏 1 {\displaystyle{\displaystyle{\displaystyle Q_{n}\!\left(\thalf(aq^{-x}+a^{-1}q% ^{x});a,b\,;\,q^{-1}\right):=(-1)^{n}b^{n}q^{-\frac{1}{2}n(n-1)}\left((ab)^{-1% };q\right)_{n}\qHyperrphis{3}{1}@@{q^{-n},q^{-x},a^{-2}q^{x}}{(ab)^{-1}}{q}{q^% {n}ab^{-1}}}}}
