Recurrences of Stirling and Lah numbers via second kind Bell polynomial

open access: yesDiscrete Mathematics Letters, 2020
Summary: In the paper, by virtue of several explicit formulas for special values and a recurrence of the Bell polynomials of the second kind, the authors derive several recurrences for the Stirling numbers of the first and second kinds, for 1-associate Stirling numbers of the second kind, for the Lah numbers, and for the binomial coefficients.

Asymptotics of stirling numbers of the second kind [PDF]

open access: yes, 1972
A complete asymptotic development of the Stirling numbers S(N,K) of the second kind is obtained by the saddle point method previously employed by Moser and Wyman [Trans. Roy. Soc.

Extended degenerate Stirling numbers of the second kind and extended degenerate Bell polynomials

open access: yes, 2017
In a recent work, the degenerate Stirling polynomials of the second kind were studied by T. Kim. In this paper, we investigate the extended degenerate Stirling numbers of the second kind and the extended degenerate Bell polynomials associated with them.

R-Bell Numbers for Graphs

open access: yes, 2014
The r-Bell number B^r(G) of a simple labeled graph G is the number of partitions of its vertex set whose blocks are independent sets of G where the first r-vertices are in different blocks.

A theorem relating potential and bell polynomials

open access: yes, 1982
We define the potential polynomial F(z)k and the exponential Bell polynomial Bn,j (0,...,0, ƒrƒr+1,...) and we prove a theorem relating the two. Though not well-known, the theorem has many applications, some of which we discuss in this paper.

Generalizations of Bell number formulas of spivey and Mező

open access: yes, 2016
We provide q-generalizations of Spivey?s Bell number formula in various settings by considering statistics on different combinatorial structures. This leads to new identities involving q-Stirling numbers of both kinds and q-Lah numbers.

Probabilistic degenerate r-Stirling numbers of the second and probabilistic degenerate r-Bell polynomials

open access: yes
Assume that Y is a random variable whose moment generating function exists in a neighborhood of the origin. We study the probabilistic degenerate r-Stirling numbers of the second kind associated with Y and the probabilistic degenerate r-Bell polynomials ...

q-Stirling sequence spaces associated with q-Bell numbers

open access: yesOpen Mathematics
In this study, we build qq-analog of the qq-Stirling matrix involved qq-Bell numbers Sq=(Snk(q)){{\mathbb{S}}}_{q}=({S}_{nk}\left(q)) defined by Sq=(Snk(q))=Sq(n,k)Bq(n),0≤k≤n,0,otherwise.\begin{array}{r}{{\mathbb{S}}}_{q}=({S}_{nk}\left(q))=\left ...

Partition Statistics and q-Bell Numbers (q = −1)

open access: yes, 2004
We study three partition statistics and the q-Stirling and q-Bell numbers that serve as their generating functions, evaluating these numbers when q = −1.
