A characterization of the classical orthogonal discrete and q-polynomials
(Elsevier, 2007-04-01)In this paper we present a new characterization for the classical discrete and q-classical (discrete) polynomials (in the Hahn's sense).

Factorization method for difference equations of hypergeometric type on nonuniform lattices
(IOP Publishing, 2001-06-29)We study the factorization of the hypergeometric-type difference equation of Nikiforov and Uvarov on nonuniform lattices. An explicit form of the raising and lowering operators is derived and some relevant examples are given.
