Generalized Stirling Numbers I [PDF]

open access: green, 2018
We consider generalized Stirling numbers of the second kind $% S_{a,b,r}^{ _{s}, _{s},r_{s},p_{s}}\left( p,k\right) $, $% k=0,1,\ldots .rp+\sum_{s=2}^{L}r_{s}p_{s}$, where $a,b, _{s}, _{s} $ are complex numbers, and $r,p,r_{s},p_{s}$ are non-negative integers given, $s=2,\ldots ,L$.

On Stirling and bell numbers of order 1/2

open access: diamondFilomat
The Stirling numbers of order 1/2 (of the second kind) introduced by Katugampola are discussed and it is shown that they are given by a scaled subfamily of the generalized Stirling numbers introduced by Hsu and Shiue.

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 ...

Some Identities Involving $q$-Stirling Numbers of the Second Kind in Type B [PDF]

open access: yesElectronic Journal of Combinatorics, 2023
The recent interest in type B $q$-Stirling numbers of the second kind prompted us to give a type B analogue of a classical identity connecting the $q$-Stirling numbers of the second kind and Carlitz's major $q$-Eulerian numbers, which turns out to be a ...

New approach to λ-Stirling numbers

open access: yesAIMS Mathematics, 2023
The aim of this paper is to study the $ \lambda $-Stirling numbers of both kinds, which are $ \lambda $-analogues of Stirling numbers of both kinds. These numbers have nice combinatorial interpretations when $ \lambda $ are positive integers.

Some Identities Involving Degenerate Stirling Numbers Associated with Several Degenerate Polynomials and Numbers [PDF]

open access: yesRussian journal of mathematical physics, 2022
The aim of this paper is to investigate some properties, recurrence relations and identities involving degenerate Stirling numbers of both kinds associated with degenerate hyperharmonic numbers and also with degenerate Bernoulli, degenerate Euler ...

Some Identities on Degenerate $$r$$-Stirling Numbers via Boson Operators [PDF]

open access: yesRussian journal of mathematical physics, 2022
Broder introduced the r-Stirling numbers of the first kind and of the second kind which enumerate restricted permutations and respectively restricted partitions, the restriction being that the first r elements must be in distinct cycles and respectively ...

Dickson–Stirling numbers [PDF]

open access: yesProceedings of the Edinburgh Mathematical Society, 1997
The Dickson polynomialDn, (x,a) of degreenis defined bydenotes the greatest integer function. In particular, we defineD0(x,a) = 2 for all realxanda. By using Dickson polynomials we present new types of generalized Stirling numbers of the first and second kinds. Some basic properties of these numbers and a combinatorial application to the enumeration of

Note on the Higher-Order Derivatives of the Hyperharmonic Polynomials and the r-Stirling Polynomials of the First Kind

open access: yesAxioms, 2022
In this paper, we focus on the higher-order derivatives of the hyperharmonic polynomials, which are a generalization of the ordinary harmonic numbers. We determine the hyperharmonic polynomials and their successive derivatives in terms of the r-Stirling ...
