On the Higher-Order Sheffer Orthogonal Polynomial Sequences ( Preface )


In 1939, I.M. Sheffer published seminal results regarding the characterizations of polynomials via general degree-lowering operators and showed that every polynomial sequence can be classified as belonging to exactly one Type. A large portion of his work was dedicated to developing a wealth of aesthetic results regarding the most basic type set, entitled B… (More)
