q-Classical orthogonal polynomial: A general difference calculus approach
Costas-Santos, R. S.and Marcellan, F. Acta Applicandae Mathematicae 111 (2010), 107 — 128Abstract
q-Classical orthogonal polynomials of the q-Hahn tableau are characterized from their orthogonality condition and by a first and a second structure relation. Unfortunately, for the q-semiclassical orthogonal polynomials (a generalization of the classical ones) we find only in the literature the first structure relation.
In this paper, a second structure relation is deduced. In particular, by means of a general finite-type relation between a q-semiclassical polynomial sequence and the sequence of its q-differences such a structure relation is obtained.
