Moreover, in classical situations (Meixner, Charlier, Kravtchouk and Hahn), we give explicitely these difference equations; and from Hahn difference equation, we recover by limit process the difference equations satisfied by the associated of classical discrete orthogonal polynomials and differential equations satisfied by the associated of classical continuous orthogonal polynomials.
