Some identities of degenerate harmonic and degenerate hyperharmonic numbers arising from umbral calculus

open access: yesOpen Mathematics, 2023
Hyperharmonic numbers were introduced by Conway and Guy (The Book of Numbers, Copernicus, New York, 1996), whereas harmonic numbers have been studied since antiquity.

Representations by degenerate Daehee polynomials

open access: yesOpen Mathematics, 2022
In this paper, we consider the problem of representing any polynomial in terms of the degenerate Daehee polynomials and more generally of the higher-order degenerate Daehee polynomials.

λ-q-Sheffer sequence and its applications

open access: yesDemonstratio Mathematica, 2022
Recently, Kim-Kim [J. Math. Anal. Appl. 493 (2021), no. 1] introduced the degenerate Sheffer sequence and λ-Sheffer sequence. The purpose of this article is to study λ-q-Sheffer sequence and the degenerate q-Sheffer sequence, which are derived from the ...

Study of degenerate derangement polynomials by λ-umbral calculus

open access: yesDemonstratio Mathematica, 2023
In the 1970s, Rota began to build completely rigid foundations for the theory of umbral calculus based on relatively modern ideas of linear functions and linear operators.

On polynomials of Sheffer type arising from a Cauchy problem

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 33, Page 2119-2137, 2003., 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. By appealing to the methods of the operator calculus, it is possible to categorize the new functions as polynomials ...

Umbral Methods and Harmonic Numbers

open access: yesAxioms, 2018
The theory of harmonic-based functions is discussed here within the framework of umbral operational methods. We derive a number of results based on elementary notions relying on the properties of Gaussian integrals.

Towards psi-extension of Rota`s Finite Operator Calculus [PDF]

open access: yesReports on Mathematical Physics Vol. 48 No 3 (2001) : 305-342, 2004
A class of extended umbral calculi in operator form is presented. Extensions of all basic theorems of classical Finite Operator Calculus are shown to hold. The impossibility of straightforward extending of quantum q-plane formulation of the q-umbral caculus to the general psi-calculus case is demonstrated.
