Stefan Hilger, Galina Filipuk, R. A. Kycia, Alina Dobrogowska · International Journal of Difference Equations · 2014
In this paper we shall study the problem of the (q, h)-discretization (generalization) of ladder operators. We shall present a few illustrative and important examples including the Weber, Bessel and Laguerre ladders and their (q, h)-analogues.
