Second structure relation for \(q\)-semiclassical polynomials of the Hahn Tableau. (English) Zbl 1113.33022
Only the first structure theorem for the \(q\)-semiclassical orthogonal polynomials exists. The authors propose a second structure relation. In doing so, the interplay of a general finite-type relation between a \(q\)-classical polynomial and the sequence of its \(q\)-differences is exploited.
