Abstract
In this chapter, we present a rigorous development of I. M. Sheffer’s characterization of the A-Type 0 orthogonal polynomial sequences. We first develop the results that led to the main theorem that characterizes the general A-Type 0 polynomial sequences via a linear generating function. From there, we develop the additional theory that Sheffer utilized in order to determine which A-Type 0 polynomial sequences are also orthogonal. We then address Sheffer’s additional characterizations of B-Type and C-Type, as well as E.D. Rainville’s \(\sigma \) -Type classification. Lastly, we cover J. Meixner’s approach to the same characterization problem studied by Sheffer and then discuss an extension of Meixner’s analysis by W.A. Al-Salam. Portions of the analysis addressed throughout this chapter are supplemented with informative concrete examples.
