Exceptional Charlier and Hermite orthogonal polynomials

Antonio J. Duran

Using Casorati determinants of Charlier polynomials, we construct for each finite set $F$ of positive integers a sequence of polynomials $r_{n}^{F}$ , $n \in σ_{F}$ , which are eigenfunctio…

Constructing bispectral orthogonal polynomials from the classical discrete families of Charlier, Meixner and Krawtchouk

Antonio J. Durán, Manuel D. de la Iglesia

Given a sequence of polynomials $(p_{n})_{n}$ , an algebra of operators $A$ acting in the linear space of polynomials and an operator $D_{p} \in A$ with $D_{p} (p_{n}) = n p_{n}$ …
