Vector weighted Stirling numbers and an application in graph theory

open access: yesElectronic Journal of Graph Theory and Applications, 2021
We introduce \textit{vector weighted Stirling numbers}, which are a generalization of ordinary Stirling numbers and restricted Stirling numbers. Some relations between vector weighted Stirling numbers and ordinary Stirling numbers and some of their ...

Normal ordering of degenerate integral powers of number operator and its applications

open access: yesApplied Mathematics in Science and Engineering, 2022
The normal ordering of an integral power of the number operator in terms of boson operators is expressed with the help of the Stirling numbers of the second kind. As a ‘degenerate version’ of this, we consider the normal ordering of a degenerate integral

Two closed forms for the Bernoulli polynomials [PDF]

open access: yes, 2015
In the paper, the authors find two closed forms involving the Stirling numbers of the second kind and in terms of a determinant of combinatorial numbers for the Bernoulli polynomials and numbers.Comment: 7 ...

Some Identities of Degenerate Bell Polynomials

open access: yesMathematics, 2020
The new type degenerate of Bell polynomials and numbers were recently introduced, which are a degenerate version of Bell polynomials and numbers and are different from the previously introduced partially degenerate Bell polynomials and numbers.

A Family of the r-Associated Stirling Numbers of the Second Kind and Generalized Bernoulli Polynomials

open access: yesAxioms, 2021
In this article, we derive representation formulas for a class of r-associated Stirling numbers of the second kind and examine their connections with a class of generalized Bernoulli polynomials.

Asymptotics of Stirling and Chebyshev‐Stirling Numbers of the Second Kind

open access: yesStudies in Applied Mathematics, 2014
For the classical Stirling numbers of the second kind, asymptotic formulae are derived in terms of a local central limit theorem. The underlying probabilistic approach also applies to the Chebyshev–Stirling numbers, a special case of the Jacobi–Stirling numbers.

On stirling numbers of the second kind

open access: yesJournal of Combinatorial Theory, 1969
AbstractWe first find inequalities between the Stirling numbers S(n, r) for fixed n, then introduce functions L and U such that L(n, r)≤S(n, r)≤U(n, r), and finally obtain the asymptotic value n/log n for the value of r for which S(n, r) is maximal.

Generalized degenerate Bernoulli numbers and polynomials arising from Gauss hypergeometric function

open access: yesAdvances in Difference Equations, 2021
A new family of p-Bernoulli numbers and polynomials was introduced by Rahmani (J. Number Theory 157:350–366, 2015) with the help of the Gauss hypergeometric function.

Degenerate Catalan-Daehee numbers and polynomials of order r arising from degenerate umbral calculus

open access: yesAIMS Mathematics, 2022
Many mathematicians have studied degenerate versions of some special polynomials and numbers that can take into account the surrounding environment or a person's psychological burden in recent years, and they've discovered some interesting results ...

On the P-Adic Valuations of Stirling Numbers of the Second Kind

open access: yes, 2021
In this paper, we introduced certain formulas for p-adic valuations of Stirling numbers of the second kind S(n, k) denoted by vp(S(n, k)) for an odd prime p and positive integers k such that n ≥ k. We have obtained the formulas, vp(S(n, n − a)) for a = 1,
