Solutions of Umbral Dirac-Type Equations
The aim of this work is to study the method of the normalized systems of functions. The normalized systems of functions with respect to the Dirac operator in the umbral Clifford analysis are constructed.

Umbral operational techniques offer sturdy mechanism in the studies of special functions and special polynomials. The techniques of umbral calculus are employed to derive properties of families of exponential-like functions and their hyperbolic forms ...

Operational, umbral methods, Borel transform and negative derivative operator techniques
Differintegral methods, namely those techniques using differential and integral operators on the same footing, currently exploited in calculus, provide a fairly unexhausted source of tools to be applied to a wide class of problems involving the theory of special functions and not only.

Special Numbers and Polynomials Including Their Generating Functions in Umbral Analysis Methods [PDF]
In this paper, by applying umbral calculus methods to generating functions for the combinatorial numbers and the Apostol type polynomials and numbers of order k, we derive some identities and relations including the combinatorial numbers, the Apostol-Bernoulli polynomials and numbers of order k and the Apostol-Euler polynomials and numbers of order k ...

Umbral Calculus and New Trigonometries [PDF]
The present work proposes an overview of the Umbral calculus and of its wide range of applicability. The aim is to provide new tools, embedding umbral, symbolic and operatorial methods to be exploited in pure and applied Mathematics, in the research ...

Umbral Methods, Combinatorial Identities and Harmonic Numbers
We analyse and demonstrate how umbral methods can be applied for the study of the problems, involving combinatorial calculus and harmonic numbers. We demonstrate their efficiency and we find the general procedure to frame new and existent identities within a unified framework, amenable of further generalizations.

Los políticos de Umbral: retratos poéticos y antipoéticos [PDF]
This article addresses the use of poetic features in Francisco Umbral’s work by analysing his portraits of politicians. Although Umbral was not strictly speaking a poet, his texts were written in a very poetic manner, and this can be seen in those ...

Operator Ordering and Solution of Pseudo-Evolutionary Equations
The solution of pseudo initial value differential equations, either ordinary or partial (including those of fractional nature), requires the development of adequate analytical methods, complementing those well established in the ordinary differential ...
