چکیده
n m n m Z ^ . W" = 5>(w, jy^Fip, k)(k)j = Zj\S(m, j)(n, j). k=o y=o k=o j=o Notice that the special case for m = 0 is also true. Hence, (2) holds for every m > 0. • Remark Sometimes in applications of the rule function F(n, k) may involve some independent parameters. Moreover, for the particular case in which F(n, k) > 0, so that (j)(n, 0) > 0, the lefthand side of (2) divided by (j)(n, 0) may be considered as the m moment (about the origin) of a

A Generalized Summation Rule Related to Stirling Numbers
In this section and in section 2 and 3 we will generalize the summation rule obtained by L.C. Hsu [7], involving Stirling numbers of the second kind. Given four real numbers a, b, α and β with α 6= 0 and β 6= 0, L.C. Hsu and H.Q. Yu [11], L.C. Hsu and P.J. Shiue [9] defined the symmetric Stirling-type pairs (〈a, b, α, β〉pairs, for short) {s, s} = {s(n, k), s(n, k)} = {s(n, k, a, b;α, β), s(n, k...

متن کاملStirling Numbers and Generalized Zagreb Indices
We show how generalized Zagreb indices $M_1^k(G)$ can be computed by using a simple graph polynomial and Stirling numbers of the second kind. In that way we explain and clarify the meaning of a triangle of numbers used to establish the same result in an earlier reference.
متن کاملModified degenerate Carlitz's $q$-bernoulli polynomials and numbers with weight ($alpha ,beta $)
The main goal of the present paper is to construct some families of the Carlitz's $q$-Bernoulli polynomials and numbers. We firstly introduce the modified Carlitz's $q$-Bernoulli polynomials and numbers with weight ($_{p}$. We then define the modified degenerate Carlitz's $q$-Bernoulli polynomials and numbers with weight ($alpha ,beta $) and obtain some recurrence relations and other identities...
متن کاملCONVOLVING THE m-TH POWERS OF THE CONSECUTIVE INTEGERS WITH THE GENERAL FIBONACCI SEQUENCE USING CARLITZ’S WEIGHTED STIRLING POLYNOMIALS OF THE SECOND KIND
Summation rules for various types of convolutions have been the subject of much interest in The Fibonacci Quarterly. The following references are of particular relevance to this topic: Cohen and Hudson [8], Corley [9], Filipponi and Freitag [11], Gould [14], Haukkanen [15], Hsu [19], and finally Philippou and Georghiou [23]. Also consult Neuman and Schonbach’s SIAM Review article [22], where su...
متن کاملMultiple Stirling Number Identities
A remarkable multiple analogue of the Stirling numbers of the first and second kind was recently constructed by the author. Certain summation identities, and related properties of this family of multiple special numbers are investigated in the present paper.
