Jitender Singh

摘要:

引入了一个有理数序列作为Bernoulli数列的推广.然后使用Faà di Bruno公式的应用程序获得涉及这个广义序列的项的产品和。这些乘积和类似于高阶Bernoulli数,并且用于开发涉及幂和$\displaystyle Ψ_k(x,n):=\sum_{d|n}μ(d)d^k S_k(\frac{x}{d}), n\in\mathbb{Z}^+$的乘积和的封闭形式表达式,所述幂和$\displaystyle Ψ_k(x,n):=\sum_{d|n}μ(d)d^k S_k(\frac{x}{d}), n\in\mathbb{Z}^+$通过默比乌斯函数$μ$和实变量或复变数$x.$的通常幂和$\displaystyle S_k(x):=\frac{B_{k+1}(x+1)-B_{k+1}(0)}{k+1}.$来定义。

英文摘要:

A sequence of rational numbers as a generalization of the sequence of Bernoulli numbers is introduced. Sums of products involving the terms of this generalized sequence are then obtained using an application of the Faà di Bruno's formula. These sums of products are analogous to the higher order Bernoulli numbers and are used to develop the closed form expressions for the sums of products involving the power sums $\displaystyle Ψ_k(x,n):=\sum_{d|n}μ(d)d^k S_k(\frac{x}{d}), n\in\mathbb{Z}^+$ which are defined via the Möbius function $μ$ and the usual power sum $S_k(x)$ of a real or complex variable $x.$ The power sum $S_k(x)$ is expressible in terms of the well known Bernoulli polynomials by $\displaystyle S_k(x):=\frac{B_{k+1}(x+1)-B_{k+1}(0)}{k+1}.$
