Pearson Equations for Discrete Orthogonal Polynomials: III. Christoffel and Geronimus transformations
Published 6 Jul 2021 in math.CA, math-ph, math.MP, and nlin.SI | (2107.02918v2)
Abstract: Contiguous hypergeometric relations for semiclassical discrete orthogonal polynomials are described as Christoffel and Geronimus transformations. Using the Christoffel-Geronimus-Uvarov formulas quasi-determinatal expressions for the shifted semiclassical discrete orthogonal polynomials are obtained.
