Umbral calculus associated with Bernoulli polynomials [PDF]
Recently, D. S. Kim and T. Kim have studied applications of um- bral calculus associated with p-adic invariant integrals on Zp (see [6]). In this paper, we investigate some interesting properties arising from umbral calculus. These properties are useful in deriving some identities of Bernoulli polynomials.

An umbral setting for cumulants and factorial moments [PDF]
We provide an algebraic setting for cumulants and factorial moments through the classical umbral calculus. Main tools are the compositional inverse of the unity umbra, connected with the logarithmic power series, and a new umbra here introduced, the singleton umbra.

Some comments on Rota's Umbral Calculus
AbstractRota's Umbral Calculus is put in the context of general Fourier analysis. Also, some shortcuts in the proofs are illustrated and a new characterization of sequences of binomial type is given. Finally it is shown that there are few (classical) orthogonal polynomials of binomial type.

A set-theoretic interpretation of the umbral calculus
AbstractThrough the notion of enriched species, we develop a bijective calculus set-theoretic counterpart of the theory of binomial enumeration.

Formal calculus and umbral calculus [PDF]
In this paper we use the viewpoint of the formal calculus underlying vertex operator algebra theory to study certain aspects of the classical umbral calculus and we introduce and study certain operators generalizing the classical umbral shifts. We begin by calculating the exponential generating function of the higher derivatives of a composite function,

Umbral Calculus and Cancellative Semigroup Algebras [PDF]
We describe some connections between three different fields: combinatorics (umbral calculus), functional analysis (linear functionals and operators) and harmonic analysis (convolutions on group-like structures). Systematic usage of cancellative semigroup, their convolution algebras, and tokens between them provides a common language for description of ...

Cellular Signaling Networks Function as Generalized Wiener-Kolmogorov Filters to Suppress Noise
Cellular signaling involves the transmission of environmental information through cascades of stochastic biochemical reactions, inevitably introducing noise that compromises signal fidelity.

Almansi Theorems in Umbral Clifford Analysis and the Quantum Harmonic Oscillator [PDF]
We introduce the Umbral calculus into Clifford analysis starting from the abstract of the Heisenberg commutation relation $[\frac{d}{dx}, x] = {\bf id}$. The Umbral Clifford analysis provides an effective framework in continuity and discreteness. In this paper we consider functions defined in a star-like domain $\Omega \subset \BR^n$ with values in ...
