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

Determinant representations of Appell polynomial sequences
, 2008 In this paper, we develop a new representation for Appell polynomial sequence via determinants. In addition, we demonstrate a direct application of this determinant formula (representation) for Appell sequence by deriving a determinant formula for a ...

A certain class of approximation operators
, 2005 In this paper we are studying the sequences of linear positive operators (Pα,β n ) defined by means of the umbral calculus. We are proving that the sequence (Pα,β n ) converges uniformly to the identity operator and we give some results for the rate of ...

ON POLYNOMIALS OF SHEFFER TYPE ARISING FROM A CAUCHY PROBLEM
, 2003 A new sequence of eigenfunctions is developed and studied in depth. These theta polynomials are derived from a recent analytic solution of the canonical Cauchy problem for parabolic equations, namely, the inverse heat conduction problem.

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