A STUDY ON MULTI-STIRLING NUMBERS OF THE FIRST KIND

open access: hybridFractals, 2022
In this paper, we define the multi-Stirling numbers of the first kind by means of the multiple logarithm and as a generalization of the Stirling numbers of the first kind. Then we introduce two additional special numbers by using the multiple logarithm, namely the modified multi-Bernoulli numbers as a generalization of the higher-order Bernoulli ...

A Family of Generalized Stirling Numbers of the First Kind

open access: diamondApplied Mathematics, 2014
A modified approach via differential operator is given to derive a new family of generalized Stirling numbers of the first kind. This approach gives us an extension of the techniques given by El-Desouky [1] and Gould [2]. Some new combinatorial identities and many relations between different types of Stirling numbers are found.

On the $p$-adic properties of Stirling numbers of the first kind [PDF]

open access: greenActa Mathematica Hungarica, 2019
Let $n, k$ and $a$ be positive integers. The Stirling numbers of the first kind, denoted by $s(n,k)$, count the number of permutations of $n$ elements with $k$ disjoint cycles. Let $p$ be a prime. In recent years, Lengyel, Komatsu and Young, Leonetti and Sanna, Adelberg, Hong and Qiu made some progress in the study of the $p$-adic valuations of $s(n,k)$

On r-Stirling Type Numbers of the First Kind

open access: diamondTurkish Journal of Analysis and Number Theory, 2019
Some combinatorial properties of -Stirling numbers are proved. Moreover, two asymptotic formulas for -Stirling numbers of the first kind derived using different methods are discussed and corresponding asymptotic formulas for the -Stirling type numbers of the first kind are obtained as corollaries.

On Non-central Stirling Numbers of the First Kind [PDF]

open access: green, 2009
It is shown in this note that non-central Stirling numbers s(n,k,a) of the first kind naturally appear in the expansion of derivatives of the product of a power function and a logarithn function. We first obtain a recurrence relation for these numbers, and then, using Leibnitz rule we obtain an explicit formula for these numbers.

A diagonal recurrence formula for Stirling numbers of the first kind [PDF]

open access: green, 2013
In the paper, the author presents diagonal recurrence relations for the Stirling numbers of the first kind. As by-products, the author also recovers three explicit formulas for special values of the Bell polynomials of the second kind.Comment: 7 ...

The Extended Legendre-Stirling Numbers of the First Kind

open access: bronzeDEStech Transactions on Engineering and Technology Research, 2016
The Legendre-Stirling numbers of the first kind  j n Ps are defined by the coefficients of Taylor expansion of the function x(x  2)(x  6)(x  (n 1)n) by Andrews and Littlejohn (see "A combinatorial interpretation of the Legendre-Stirling numbers", Proc. Amer. Math. Soc, 137: 2581-2590, 2009). In this paper, two new kinds of numbers   jn Ps (n 
