| Mar 20, 2022 at 3:23 | comment | added | Tom Copeland | Btw, the matrices of Ex. 1 contain the coefficients of two iconic Appell Sheffer polynomial sequences--the Pascal and signed Pascal row polynomials--that are an umbral inverse pair whereas those of Ex. 2 with some zero padding are for the iconic pair of binomial Sheffer sequences which are umbral inverses. That the first pair are umbral inverses is related to their moment e.g.f.s being multiplicatively inverse while for the second pair the umbral inversion is related to compositional inversion. | |
