Sheffer sequence: Measurement, Properties & Examples

In mathematics, a Sheffer sequence or poweroid is a polynomial sequence, i.e., a sequence ( pn(x) : n = 0, 1, 2, 3, ... ) of polynomials in which the index of each polynomial equals its degree, satisfying conditions related to the umbral calculus in combinatorics. They are named for Isador M. Sheffer.
