R. Alvareznodarse et Yf. Smirnov, THE DUAL HAHN Q-POLYNOMIALS IN THE LATTICE X(S)=[S](Q)[S-ALGEBRAS SUQ(2) AND SUQ(1,1)(1](Q) AND THE Q), Journal of physics. A, mathematical and general, 29(7), 1996, pp. 1435-1451
The dual q-Hahn polynomials in the non-uniform lattice x(s) = [s](q)[s
+ 1](q) are obtained. The main data for these polynomials are calcula
ted (the square of the norm of the coefficients of the three-term recu
rrence relation, etc), as well as the lattice representation as a q-hy
pergeometric series. The connection with the Clebsch-Gordan coefficien
ts of the quantum algebras SUq(2) and SUq(1, 1) is also given.
