Sums of products involving power sums of $varphi(n)$ integers
Jitender Singh ;
Date 25 Jun 2013
AbstractA 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 Fa’a 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 $displaystyle Psi_k(x,n):=sum_{d|n}mu(d)d^k S_k(frac{x}{d}), ninmathbb{Z}^+$ which are defined via the M"obius function $mu$ 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 $displaystyle S_k(x):=frac{B_{k+1}(x+1)-B_{k+1}(0)}{k+1}.$
