Mehler--Heine asymptotics for finite differences of mass-modified Charlier and Meixner polynomials
Anier Soria-Lorente, Junior Michel
Point-mass perturbations and finite-difference operations alter the finite-degree structure of discrete orthogonal polynomials, but their combined effect at the Mehler--Heine scale…

On generating functions and Mehler--Heine formulas for discrete Charlier and Meixner Sobolev-type orthogonal polynomials
Anier Soria Lorente, Junior Michel
Generating functions are among the most important analytical tools in the theory of orthogonal polynomials, providing a unified framework for deriving structural identities, asympt…
