Lerch's and the Polylogarithm at the Positive Integers

Jose Risomar Sousa

We review the closed forms of the partial Fourier sums associated with $\HP_k(n)$ from a previous paper and create an asymptotic expression for $\HP(n)$ as a way to obtain formulae…

The Hurwitz Zeta Function at the Positive Integers

Jose Risomar Sousa

A formula for the Hurwitz zeta function at the positive integers , , is created by solving the real and the imaginary parts separately and then combining them. A few di…

Generalized Harmonic Progression

Jose Risomar Sousa

This paper presents formulae for the sum of the terms of a harmonic progression of order with integer parameters, , and for the partial sums of its two associ…

Generalized Harmonic Numbers

Jose Risomar Sousa

This paper presents new formulae for the harmonic numbers of order , , and for the partial sums of two Fourier series associated with them, denoted here by $C^m_{k}(n)…

A Reformulation of the Riemann Hypothesis

Jose Risomar Sousa

We present some novelties on the Riemann zeta function. Using an extended formula created for the polylogarithm in a previous paper, , the zeta function's D…

Lerch's and the Polylogarithm at the Negative Integers

Jose Risomar Sousa

At the negative integers, there is a simple relation between the Lerch function and the polylogarithm. Starting from that relation and a formula for the polylogarithm at the n…
