q-Laguerre polynomials and big q-Bessel functions and their orthogonality relations

Nicola Ciccoli, Erik Koelink, Tom H. Koornwinder

The q-Laguerre polynomials correspond to an indetermined moment problem. For explicit discrete non-N-extremal measures corresponding to Ramanujan's ${}_1{\psi }_1$-summation we complemen…
