 Finite Series in Connection with Apéry, Pi Constant

The n-th partial sums below are true for each positive integer n.

• (I)

• (II)

The notations and in (I) and (II) represent the special values of a new generic formula that we define it as an extensive notation from Hurwitz zeta function [1*] for n-th partial sum as follows ,

where s and a are complex variables with Re(s) > 1 and Re(a) > 0.

When n tends to infinity, the extensive notation [2*] is then expressed as .

Special Case

• n = ∞:

In the limit as n approaches to infinity, both series (I) and (II) converge and its values are , where is Apéry's constant. .

Example

• If we put n = 2, both sides of (II) are equal to 29/31752, namely .

[2*] The purpose of our website is to show a beauty of series.  We introduce a new extension of the notation of Hurwitz zeta function for n-th partial sum because there exist such series (I) and (II).  We share our results on the internet.  The acceptance of this notation is the work of other men.
