Abstract

This paper presents new formulae for the harmonic numbers of order kk, Hk(n)H_{k}(n), and for the partial sums of two Fourier series associated with them, denoted here by Ckm(n)C^m_{k}(n) and Skm(n)S^m_{k}(n). I believe this new formula for Hk(n)H_{k}(n) is an improvement over the digamma function, ψ\psi, because it's simpler and it stems from Faulhaber's formula, which provides a closed-form for the sum of powers of the first nn positive integers. We demonstrate how to create an exact power series for the harmonic numbers, a new integral representation for ζ(2k+1)\zeta(2k+1) and a new generating function for ζ(2k+1)\zeta(2k+1), among many other original results. The approaches and formulae discussed here are entirely different from solutions available in the literature.
