The LaTeX DLMF and DRMF macro \AlSalamChihara represents 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:

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

These are defined by Q n ⁑ ( x ; a , b | q ) := ( a ⁒ b ; q ) n a n ⁒ \qHyperrphis ⁒ 32 ⁒ @ ⁒ @ ⁒ q - n , a ⁒ e i ⁒ ΞΈ , a ⁒ e - i ⁒ ΞΈ ⁒ a ⁒ b , 0 ⁒ q ⁒ q assign Al-Salam-Chihara-polynomial-Q 𝑛 π‘₯ π‘Ž 𝑏 π‘ž q-Pochhammer-symbol π‘Ž 𝑏 π‘ž 𝑛 superscript π‘Ž 𝑛 \qHyperrphis 32 @ @ superscript π‘ž 𝑛 π‘Ž 𝑖 πœƒ π‘Ž 𝑖 πœƒ π‘Ž 𝑏 0 π‘ž π‘ž {\displaystyle{\displaystyle{\displaystyle Q_{n}\!\left(x;a,b\,|\,q\right):=% \frac{\left(ab;q\right)_{n}}{a^{n}}\,\qHyperrphis{3}{2}@@{q^{-n},a{\mathrm{e}^% {i\theta}},a{\mathrm{e}^{-i\theta}}}{ab,0}{q}{q}}}}
