A generating function for non-standard orthogonal polynomials involving differences: the Meixner case
Juan J. Moreno-Balcazar, Teresa E. Perez, Miguel A. Pinar
In this paper we deal with a family of non--standard polynomials orthogonal with respect to an inner product involving differences. This type of inner product is the so--called …
