Explicit estimates for the Stirling numbers of the second kind [PDF]

open access: green
We give explicit estimates for the Stirling numbers of the second kind $S(n,m)$. With a few exceptions, such estimates are asymptotically sharp. The form of these estimates varies according to $m$ lying in the central or non-central regions of $\{1,\ldots ,n\}$.

Some identities involving degenerate Stirling numbers arising from normal ordering

open access: yesAIMS Mathematics, 2022
In this paper, we derive some identities and recurrence relations for the degenerate Stirling numbers of the first kind and of the second kind, which are degenerate versions of the ordinary Stirling numbers of the first kind and of the second kind.

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.

Degenerate r-truncated Stirling numbers

open access: yesAIMS Mathematics, 2023
For any positive integer $ r $, the $ r $-truncated (or $ r $-associated) Stirling number of the second kind $ S_{2}^{(r)}(n, k) $ enumerates the number of partitions of the set $ \{1, 2, 3, \dots, n\} $ into $ k $ non-empty disjoint subsets, such that ...

Explicit formulas for computing Bernoulli numbers of the second kind and Stirling numbers of the first kind [PDF]

open access: yes, 2013
In the paper, by establishing a new and explicit formula for computing the $n$-th derivative of the reciprocal of the logarithmic function, the author presents new and explicit formulas for calculating Bernoulli numbers of the second kind and Stirling ...
