Integration in the umbral calculus

open access: yesJournal of Mathematical Analysis and Applications, 1980
AbstractThe adjointness between “multiplication” and “derivation” is a recurrent theme in Rota's umbral calculus. The subject of this paper is the companion adjointness between “division” and “integration.”

Baxter Algebras and Umbral Calculus

open access: yes, 2004
We apply recent constructions of free Baxter algebras to the study of the umbral calculus. We give a characterization of the umbral calculus in terms of Baxter algebra. This characterization leads to a natural generalization of the umbral calculus that include the classical umbral calculus in a family of $ $-umbral calculi parameterized by $ $ in the
