The r-Stirling numbers

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.

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 ...

On the maximum of r-Stirling numbers

open access: yesAdvances in Applied Mathematics, 2008
\textit{A. Z. Broder} [Discrete Math. 49, 241--259 (1984; Zbl 0535.05006)] extensively studied \(r\)-Stirling numbers, which seem to have been introduced by Carlitz. By definition, the \(r\)-Stirling number of the first kind, \({n \brack m}_r\) counts the number of permutations of \(\{1,2,\ldots,n\}\) with \(m\) cycles, where the numbers \(1,2,\ldots,r\

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.

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.

Degenerate weighted Stirling numbers

open access: yesDiscrete Mathematics, 1985
The author defines generalized weighted Stirling numbers of the first and second kinds, \(S_1(n,k, \lambda\mid \theta)\) and \(S(n,k,\lambda\mid \theta)\), with two continuous parameters \(\lambda\) and \(\theta\) in addition to the two integer parameters \(n\) and \(k\) of the ordinary Stirling numbers.
