Definition

The polynomials are given in terms of basic hypergeometric functions and the q-Pochhammer symbol by ¹

p n ( x ; a , b , c , d | q ) = a − n e − i n u ( a b e 2 i u , a c , a d ; q ) n 4 ϕ 3 ( q − n , a b c d q n − 1 , a e i ( t + 2 u ) , a e − i t ; a b e 2 i u , a c , a d ; q ; q ) {\displaystyle p_{n}(x;a,b,c,d|q)=a^{-n}e^{-inu}(abe^{2iu},ac,ad;q)_{n}{}_{4}\phi _{3}(q^{-n},abcdq^{n-1},ae^{i{(t+2u)}},ae^{-it};abe^{2iu},ac,ad;q;q)}

x = cos ⁡ ( t + u ) {\displaystyle x=\cos(t+u)}
