Generalized Bell Polynomials and the Combinatorics of Poisson Central Moments

Nicolas Privault

Abstract


We introduce a family of polynomials that generalizes the Bell polynomials, in connection with the combinatorics of the central moments of the Poisson distribution. We show that these polynomials are dual of the Charlier polynomials by the Stirling transform, and we study the resulting combinatorial identities for the number of partitions of a set into subsets of size at least $2$.
