Barnes-type Daehee polynomials [PDF]

open access: yes, 2014
In this paper, we consider Barnes-type Daehee polynomials of the first kind and of the second kind. From the properties of Sheffer sequences of these polynomials arising from umbral calculus, we derive new and interesting identities.Comment: 34 ...

On the computation of classical, boolean and free cumulants

open access: yes, 2008
This paper introduces a simple and computationally efficient algorithm for conversion formulae between moments and cumulants. The algorithm provides just one formula for classical, boolean and free cumulants.

A combinatorial identity for studying Sato-Tate type problems [PDF]

open access: yes, 2010
We derive a combinatorial identity which is useful in studying the distribution of Fourier coefficients of L-functions by allowing us to pass from knowledge of moments of the coefficients to the distribution of the coefficients.Comment: This paper ...

A generalization of the "probléme des rencontres" [PDF]

open access: yes, 2018
In this paper, we study a generalization of the classical \emph{probl\'eme des rencontres} (\emph{problem of coincidences}), consisting in the enumeration of all permutations $ \pi \in \SS_n $ with $k$ fixed points, and, in particular, in the ...

An instance of umbral methods in representation theory: the parking function module

open access: yes, 2008
We test the umbral methods introduced by Rota and Taylor within the theory of representation of symmetric group. We define a simple bijection between the set of all parking functions of length $n$ and the set of all noncrossing partitions of $\{1,2,...,n\
