LAGUERRE–FREUD EQUATIONS FOR THE RECURRENCE COEFFICIENTS OF SOME DISCRETE SEMI-CLASSICAL ORTHOGONAL POLYNOMIALS OF CLASS TWO
In this paper, we give Laguerre–Freud equations for the recurrence coefficients of discrete semi-classical orthogonal polynomials of class two, when the polynomials in the Pearson equation are of the same degree. The case of generalized Charlier polynomials is also presented.
