Generalized ZETA function

  1. Oct 30, 2009 #1
    given the function [tex] Z(s)= \prod _{k=0}^{\infty}\zeta (s+k) [/tex] with [tex] \zeta (s) [/tex] being the Riemann Zeta function

    the idea is if ALL the roots have real part (i mean Riemann Hypothesis) is correct, then what would happen with the roots of Z(s) ??

    what would be the Functional equation relating Z(1-s) and Z(s) ¿¿ from the definition of Riemann functional equation

    For which values of s does Z(s) exist? A necessary condition for an infinite product to converge is that the individual terms converge to 1. Thus, it must be true that

    [tex]\zeta(s + k) \rightarrow 1[/tex] as [tex]k \rightarrow \infty[/tex]

    It's not clear to me for which values of s this holds.

    True for Re s > 1, right? And therefore true for all s ...

    Yes, that's right. Thanks!
