The r-Stirling numbers [PDF]

open access: yesDiscrete Mathematics, 1984
Let \(N(n,m,r)\) denote the number of permutations of \(\{1,\ldots,n\}\) with \(m\) cycles and such that the numbers \(1,\ldots,r\) occur in distinct cycles, and let \({\mathcal N}(n,m,r)\) denote the number of partitions of \(\{1,\ldots,n\}\) into \(m\) non-empty disjoint sets such that \(1,\ldots,r\) are in distinct subsets.

Asymptotics of Stirling and Chebyshev‐Stirling Numbers of the Second Kind [PDF]

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.

Negative $q$-Stirling numbers [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2015
The notion of the negative $q$-binomial was recently introduced by Fu, Reiner, Stanton and Thiem. Mirroring the negative $q$-binomial, we show the classical $q$ -Stirling numbers of the second kind can be expressed as a pair of statistics on a subset of ...

SOME REMARKS ABOUT STIRLING NUMBERS OF THE SECOND KIND

open access: yesHuman Research in Rehabilitation, 2013
In this paper we give a representation of Stirling numbers of the second kind, we obtain explicit formulas for some cases of Stirling numbers of the second kind and illustrate a method for founding other such formulas.

q-Bernoulli Numbers Associated with q-Stirling Numbers [PDF]

open access: yesAdvances in Difference Equations, 2008
We consider Carlitz q-Bernoulli numbers and q-Stirling numbers of the first and the second kinds. From the properties of q-Stirling numbers, we derive many interesting formulas associated with Carlitz q-Bernoulli numbers. Finally, we will prove βn,q=â

Arithmetic Identities Involving Genocchi and Stirling Numbers [PDF]

open access: yesDiscrete Dynamics in Nature and Society, 2009
An explicit formula, the generalized Genocchi numbers, was established and some identities and congruences involving the Genocchi numbers, the Bernoulli numbers, and the Stirling numbers were obtained.

A Newton Interpolation Approach to Generalized Stirling Numbers [PDF]

open access: yesJournal of Applied Mathematics, 2012
We employ the generalized factorials to define a Stirling-type pair {s(n,k;α,β,r),S(n,k;α,β,r)} which unifies various Stirling-type numbers investigated by previous authors.
