On differential equations for Sobolev-type Laguerre polynomials
J. Koekoek, R. Koekoek, H. Bavinck
We obtain all spectral type differential equations satisfied by the Sobolev-type Laguerre polynomials. This generalizes the results found in 1990 by the first and second author in…

On a difference equation for generalizations of Charlier polynomials
Herman Bavinck, Roelof Koekoek
In this paper we obtain a set of polynomials which are orthogonal with respect to the classical discrete weight function of the Charlier polynomials at which an extra point mass at…
