A Note on the Dunkl-Appell Orthogonal Polynomials

This paper deals with the problem of finding all orthogonal polynomial sets which are also $T_{\mu}$-Appell where $T_{\mu}, \mu \in \mathbb{C}$ is the Dunkl operator. The resulting polynomials reduce to Generalized Hermite polynomials $\{{{H}}_n(\mu)\}_{n\geq0}$.

Keywords:

Orthogonal polynomials, Dual sequence Dunkl operator,
