Talk:Perron's formula

From Wikipedia, the free encyclopedia

The examples seem to be examples of Abel's formula, rather than Perron's.--DCo1 22:40, 31 August 2006 (UTC)

Answer: = In fact Perron's inversion formula, is just an example of application of Abel-sum formula (more complicate derivations of Perron's formula are known, i have put the easiest) another direct conclussion or derivation from Abel-sum formula is the identity:

log\zeta (s)=s\int_{2}^{\infty}dx\frac{\pi (x)}{x(x^{s}-1)}

In this article, the function A(x) should be defined somewhere !? —Preceding unsigned comment added by 141.84.69.20 (talk) 23:38, 31 May 2008 (UTC)
